X pipe

[LTb1ow]

So I have been toying with the idea of buying an X pipe kit and running dumps before the axle. Summit has a nice one with cutouts in the X and stainless for 170 ish... that being said, will it be possible to have a nice deep sound at idle but not the blaring ness of an open Y car...?

Any thoughts of good mellow ish mufflers?

[BonzoHansen]

Dumps can be very loud in a car - especially a hatch back, regardless of muffler brand. That said, don't overlook dynomax ultra-flows for reasonable sound & good airflow.

I'd remind you of the illegality of it but you'll cry, so I won't. :)

W/ the LT1's firing order thats going to be obnoxiously loud, you could quiet it down w/ a dynomax superturbo muffler. Great flow and really quiet. That should have you in the high 13's in no time :|.

[Slow Z]

Single 3" exhaust with tailpipes rule

[LTb1ow]

Why?

Mine is way to quiet and I don't wanna drop a huge amount of money on another cat back. X pipe will flow better and give me much more choice on mufflers.

You could run any muffler you want with a single 3"... Way cheaper than redoing the whole exhaust, losing ground clearance, and making your car loud and stinky inside with dumps.

My car has trapped 121mph on motor in a 1/4 mile through single 3" exhaust - it's not nearly as restrictive as people think. 8-)

[LTb1ow]

Well ok, heres the thing, its an expensive cat back and I do not wanna cut it up. So a cheap X pipe for ****s and giggles would be more fun to screw with. As for smelling, my car does that already.

[Anti_Rice_Guy]

slaptastic had dumps on his car and hated it (kick up dirt/dust, drone, obnoxious sound under your a$$), now has 3" true duals with no mufflers and loves it. Or at least I love it :lol:

[LTb1ow]

The idea is less weight, 3" true duals would weight a lot.

[JerzLT1]

You can't run a chassis mount TQ arm but I'll sell you the one off of me car for $100

[LTb1ow]

How loud is it?

[Anti_Rice_Guy]

The idea is less weight, 3" true duals would weight a lot.

3" TDs are also expensive...I was just stating that he hated the dumps, and preferred tailpipes, to let you know what it was like when he had them. IMO it sounds better with tailpipes as well.

[LTb1ow]

I don't run tips now anyway, I like the look better.

[JerzLT1]

Loud as he'll at wot, but if you have sound deadening you can have a conversation while cruising

[LTb1ow]

How is it at idle?

Thats the part I need deep and mellow... don't wanna be banned from any more neighborhoods....

[JerzLT1]

It's really deep, i'll bring it to the south meet if your going. Makes my LE cam sound great

[LTb1ow]

Yea, with an open Y my cam sounds awesome, but way way way to loud for DD use.

I may be going to the south meet, dunno yet.

It can be "legal" (all other things aside) if it is not exessively loud and it exits gases behid the axle correct?

[sweetbmxrider]

actually its kind of biased because the inspector can choose whether or not its a failure. i'm sure if they have to get on their stomach to probe the car, they are going to fail it :D

[LTb1ow]

Yea, well, LTs fail me anyways. Just saying I "could" make it legal ish to please the yuppies on NJFBOA (;)) ...

[sweetbmxrider]

with dumps? uh no. are you planning on a chambered muffler? some places (etown) wont let you run without a chambered muffler....yuppies

[LTb1ow]

Nah, I meant if I ran em over the axle.

[sweetbmxrider]

oh true

[NastyEllEssWon]

i just got rid of my true duals and x pipe. it sounds great to be honest...but the whole reason i found it wasnt for me cause i wanted to run a chassis mount torque arm, so i traded for a y pipe and single exhaust to gain the room. it feels a tad bit slower without the duals now....if you exit it out the back it sounds good. i have pics of it and all if you want pm me i can link you...dont wanna jack your thread





edit: if your looking for a straight through muffler style check out tsp. a friend of mine has an ss with a tsp x pipe and dumps. it sounds crazy good

[LTb1ow]

Well I would keep the ORY/catback, so worst case swap exhausts. Just want some thing more agressive.

[JerzLT1]

Mine will be off in the next few weeks if your interested. It's a custom ttp setup

[LTb1ow]

Yea I still gotta listen to it, been stuck in class all day.

[LTb1ow]

Just listened to your youtube clip, sounds very nice man!

[Tru2Chevy]

In NJ the exhaust has to exit at the side or rear of the vehicle at least 4" after any window that you can roll down. So on a 4th gen, the exhaust has to come to (near?) the edge of the body anywhere behind the rear wheels.

- Justin

[LTb1ow]

So I could theoretically have 90 degrees after the mufflers and shoot em out the side in front of the wheels?

[Tru2Chevy]

So I could theoretically have 90 degrees after the mufflers and shoot em out the side in front of the wheels?

I don't think there is enough space there. Go measure from the rearmost point of your side window to the leading edge of the wheelwell. You'll need at least 7" there to run a 3" tip out the side.

[NastyEllEssWon]

deff not legal

[LTb1ow]

Deff loud as hell too, lol.

Nah still thinking it over, so no rush.

[Frosty]

I don't mean any disrespect but why are you hacking up this poor car? Between wanting to move fuel lines and some small solenoid that's not bothering anything and now wanting run dumps on a car that traps at a 105mph...I don't know...it seems like you're trying to do all of this stuff when you have other issues to handle. Even if your car was faster it's still a waste.

You're taking an average street car and ruining the drivability and practicality. To each their own but it's not like you own some 10 second car that sees the track all of the time.

With that said, if you're hell-bent on running duals definitely listen to Bonzo.

if you have it done like that and have the piping routed a bit more to the passenger side you can prolly still run a chassis mount t/a too :nod:

[LTb1ow]

IDK, a chassis mount torque arm would replace the stock and that may come off as hacking my poor ole car....
:rollseye:

IDK still thinking of a few different options...

Do you have to whine every time someone shows a little bit of criticism? Seriously dude...every time someone doesn't agree with your idea you whine like a ****ing 5yr that just had a piece of candy stolen.

I'll take your word for it about your car being more than an average street car..I saw your trap speed and I guess it's all in the driver.

I was just trying to show some respectable criticism...like I said, to each their own...it just seems like you're making more work for yourself. Sorry for trying to help and provide a different point of view.

BTW, adding a supercharger isn't hacking up a car like your IM said...nice try though. You might want to try the driver mod before adding any more power mods to your car. :rofl:

...and WTF....your original response to my post isn't showing up...I think the board ate it, lol.

[LTb1ow]

nah I deleted it, dunno why your getting all hissy. I tried to IM you instead of arguing on this thread...

Ah well. I am open to ideas, but I just don't understand your point.

[Frosty]

Fair enough.

[LTb1ow]

But you still need to explain to me how an X pipe would be hacking up my car any more than a regular catback...lol

[NastyEllEssWon]

dumps on the street are gonna be rough. is your car lowered?

[LTb1ow]

Nope.

[sweetbmxrider]

its an lt1, we gotta at least try to make them look cool :-P

[WildBillyT]

But you still need to explain to me how an X pipe would be hacking up my car any more than a regular catback...lol

I know you aren't looking for a lecture, so just skip this is you want. But I'm having Wayfast flashbacks over here.

What you should do is stick to a critical path with your car. Fix what's messed up and needs to be addressed FIRST before you go solving problems you don't have, or modding something (that gives no real "gain") that creates more problems you don't need.

If you NEED an exhaust system and don't mind getting hassled by the 'man (keep in mind, this is going to be pretty loud) go ahead and do it. I've heard the summit x-pipes are pretty decent. Keep in mind that this exhaust will not be legal for reasons Justin mentioned.

If you don't NEED an exhaust system, save the cash or put it towards some other flaw with the car that keeps it from knocking down the times it should.

Precisely. It's your car and money so do what you want but if you want to be louder then add horsepower not bigger exhaust. Big pipes on a mildly modified motor will do nothing but make noise - If that's what you want then go ahead but in reality you just come off as obnoxious. Any quality single 3" catback will flow enough to make serious HP... Once again, look at my car for proof of this.

Loud but slow = :banghead:
Quiet but fast = :shock:

[Frosty]

But you still need to explain to me how an X pipe would be hacking up my car any more than a regular catback...lol

I shouldn't have used the word hack since I don't mean "OMG look at the crap work that shop did, what hack work".

What I mean is you're making the car less and less streetable. Now if that's your thing, cool. I'm telling you now a LT1 with true duals and dumps is going to be insanely loud....are you sure you're going to be able to deal with it? It might be "cool" for the first few months but what if you grow tired of it? What will you neighbors think? Will the cops harass you in your town? What if you lose some ground clearance, now suddenly your grimacing every time you come up to a big speed bump or a steep driveway? These are all things to think about...I'm by no means an expert on your car since most of your mods are top secret CIA classified info ;) but regardless....is everything else on the car 100%? Is it running the best it possibly can?

Like I've said, along with others, it's your car and your $$ so by all means spend it how you see fit but I'd hate to see you go through all of the trouble of doing an exhaust like that then hating it a few months later because it's causing more aggravation than it's worth.

I don't remember every post in this thread so I'm not sure if it's been recommended or ruled out but have you considered a cutout?

[sweetbmxrider]

he was considering the cable cut-outs, that was shot down. thankfully.

get a fuel pump and a good tune

[NastyEllEssWon]

honestly ill remember the words the guys at mufflex said when they saw my true duals that i have.....''holy crap you have 500 lbs worth of exhaust for a 400 hp car''



its true man. save the money. save the weight. get that thing moving at least past where stock lt1's are running. youve modded your car, increased your trap but lowered your 1/4 mile. why not work on that....and its almost free...just cost of track time :nod:

Good call nasty.

[LTb1ow]

Woah.

Being reminded of wayfast. fml.

I was just thinking of cheap alternatives to a cat back. And I would imagine an X pipe would be lighter than a stainless catback no?

[WildBillyT]

Woah.

Well, what's wrong with the performance of your exhaust system now? Weight does not count, and noise is easily changed.

Yeah, I thought the WF thing might be a bit much, but it is eerily reminiscent.

[JerzLT1]

Duals with dumps are lighter then a full cat back, I used to DD a car with true duals with just full bolt-ons. I agree that you should work out some bugs because you should be trapping higher butif you want to do exhaust then it's your car and do what you want

[sweetbmxrider]

that muffler on there now is definitely holding back some IMO

[LTb1ow]

Yea its a tiny muffler compared to most.

B&B triflow.

[98tadriver]

bah just run a single straight pipe from the Ypipe all the way out to the back

[LTb1ow]

Thats an idea I was throwing around, but would I be able to run it at the track like that?

I know your car is that way so idk.

[WildBillyT]

Yea its a tiny muffler compared to most.

B&B triflow.

You are going to ditch a $1000 Billy Boat exhaust for a Summit X-pipe?

[LTb1ow]

Yea... well I have mentioned I few times I would not be cutting it up or selling it.

I wonder if I can find what it flows.

[98tadriver]

Thats an idea I was throwing around, but would I be able to run it at the track like that?

I know your car is that way so idk.

at Atco, youll be fine. thats the only track i run at and dont have any problems lol.

[LTb1ow]

Yea I have the older version, so no flow numbers on their website.

[WildBillyT]

Yea I have the older version, so no flow numbers on their website.

What is your config? Headers/high flow cats/B&B?

[LTb1ow]

LTs, ORY, B&B.

[MonmouthCtyAntz]

Dude if I read your mod list correctly your running a llyold head and Cam package w/ a stall..Only trapping 105 I think your problem lies deeper then some weight issues or a catback choking up your setup...BB triflo is one of the best out there. I ran close to your traps in my 97 w/ cai,shorty headers, and a flowmaster catback.

[NastyEllEssWon]

i trapped 104 last year in my stock z28 :nod:


i think you need to take another look at that pcm for less tune.

[LTb1ow]

I have a mod list somewhere? LOL

Yea, I would say its 100% driver fail. Its been driven for a year now, so if it was something internal I think it would have failed already. No leaking fluids internally, very good oil pressure, and good tires.

I am talking to my tuner now, so he is tweaking the tune and adding in the change for gears, which hopefully will help.

With any luck, I will pull off the muffler like Ron suggested and bring it to the track again.

But all things aside, I kinda posted this thread mainly to see if an X pipe was a viable option to making my car a bit louder... B&B may be great, but its very tame.

[MonmouthCtyAntz]

i trapped 104 last year in my stock z28 :nod:


i think you need to take another look at that pcm for less tune.

Yea that was a LS1...Im talking my old a4 LT:mrgreen:. Hotcam / sniffer friendly cam only cars usually trap around 107-109ish so you should atleast be running that..How aggresive is the cam? It might be the tune but I highly doubt it has anything to do w/ your catback.

[LTb1ow]

Its a tiny muffler, like tiny.

And my cam is well, not a small cam, and not a huge cam.

[WildBillyT]

Its a tiny muffler, like tiny.

And my cam is well, not a small cam, and not a huge cam.

Physical size is not an accurate indicator of performance. I installed 2 3.5" Dynomax bullets on a Chevelle (big enough to easily push a tennis ball through) and they are only 18" long and 5" in diameter.

[NastyEllEssWon]

i know its night and day with ls and lt...i was just saying thats a stock car. he has heads and cam. you only ran it once too iirc man....stop trying to ''fix'' poop and actually see where you can get it with practice.

[LTb1ow]

I am not sure whether I said it or not, but if the idea here is than an X pipe will solve everything and get me into the 13s, then sorry, the original intent was just to have a lighter, and louder sounding exhaust.

[WildBillyT]

I am not sure whether I said it or not, but if the idea here is than an X pipe will solve everything and get me into the 13s, then sorry, the original intent was just to have a lighter, and louder sounding exhaust.

I dunno, those two reasons would not be good enough justification to replace your existing system. In my opinion of course.

[LTb1ow]

Well a cutout would be the other option, but that would be more expensive than picking up an X setup.

And I think a cutout would sound worse too.

[NastyEllEssWon]

well you know for sure an x pipe and true dual dumps is gonna outflow any y pipe you can get. if your just looking for sound then you should look back into the cutout again...sound isnt a good reason to toss out a perfectly good exhaust...especially if its as good as everyone else is saying.



you could do what i did. put an ad on ls1tech looking for someone to trade. i had to drive to CT to make the trade but it was worth it. why not look around into something like that

[LTb1ow]

I would never get rid of my catback, its original from back in 1995... LOL sentimental attachment I suppose...

I may pull the muffler off and slap a down turn on, see how it sounds. One of the tips needs to be fixed anyways. Speed bumps ftl. :(

[Frosty]

Wait, you're an auto trapping at 105 with heads/cam? Holy ****, I thought you had a 6-speed...dude....you need to some things looked at...there's no way you should be trapping that low.

[NastyEllEssWon]

Speed bumps ftl. :(





wouldnt get any better with duals dumped before the axle :wink:

[LTb1ow]

Eh, I would not care as much if I dented my 100 dollar X pipe...

[WildBillyT]

Eh, I would not care as much if I dented my 100 dollar X pipe...

You do realize that the $100 X-pipe is aluminized, not stainless, has no flanges, and requires assembly...

[NastyEllEssWon]

then just get a cheap x pipe and 20 dollar summit bullets

[LTb1ow]

You do realize that the $100 X-pipe is aluminized, not stainless, has no flanges, and requires assembly...

Yup, currently my setup is slip fit, and I have no problem with assembling things... just need an instruction manual... :mrgreen::wink:

Nah, I will just leave my setup now, if funds permit, try and pick up an electric cutout.

[NastyEllEssWon]

4 pages and he goes with the original plan.....






Yeah, I thought the WF thing might be a bit much, but it is eerily reminiscent.




:rofl::rofl::rofl:

:nod:

[LTb1ow]

Hardly. I would love an X pipe, but at the same time, a lot of good points were made against it... one day perhaps.

[MonmouthCtyAntz]

i know its night and day with ls and lt...i was just saying thats a stock car. he has heads and cam. you only ran it once too iirc man....stop trying to ''fix'' poop and actually see where you can get it with practice.

Its an automatic car...practice isnt going to fix his really low trap speed.

[Tru2Chevy]

Its an automatic car...practice isnt going to fix his really low trap speed.

Yes it will....the low trap on his one and only pass was a result of him spinning from the time he launched the car until somewhere close to the 330' mark since he didn't heat up the drag radials.

If he hooked it and only trapped 105, then I'd say he has issues.

- Justin

[LTb1ow]

That and I had a 6k in the 6AL and thought I didn't....

[Anti_Rice_Guy]

Its an automatic car...practice isnt going to fix his really low trap speed.

For launching, hell yes it will. I ran on regular tires and spun like mad at the track and killed my time/mph. 15.1 @ 96. With more practice that could be way better. Hit the limiter in 1st, 2nd, 3rd, no matter when I backed off.

[sweetbmxrider]

damn, justin's good. thats exactly what happened. freakin newb :lol:

Didnt know all the details...Thought is was just a bad short time...wasnt aware he was spinning down the track...Then yea get some et streets and get a few more passes.:nod:

[Anti_Rice_Guy]

He has drag radials IIRC but rolled through the waterbox

Ahh, let me guess Atco? lol

[LTb1ow]

Yup.

[NastyEllEssWon]

go to etown and go round the water box :nod: you just wont get as many runs as you do at atco

[Anti_Rice_Guy]

Or come to Island and have the best of both worlds...go around the water box AND get a ton of runs in :-P

[LTb1ow]

Island is a hike for me. Maybe one day.

[Anti_Rice_Guy]

Island is a hike for me. Maybe one day.

How far are you from Atco?

[LTb1ow]

Prob roughly the same distance to island, that was a fail on Al's part. Etown is like a 1/2 hr.

[Anti_Rice_Guy]

Prob roughly the same distance to island

Thus my point. :lol:

[LTb1ow]

Yea, well I don't wanna do that again is my point ;)

[JerzLT1]

You guys are too much lol, if you want a loud exhaust with a nice tone throw an x-pipe on and do dumps like you want. I don't think everyone gets the point that your looking g for sound and aren't happy with your current setup

[LTb1ow]

Woah, just re read all this... aha... yea


So I have an X pipe in case no one knew, it was free, and I do all my work, so it cost me nothing. ;)

That being said, I have already gotten a written warning from the grand ole state of NJ.

I am contemplating either a) throwing my catback back on or b) getting a pair of actual mufflers.

Its a three inch X with a pair of sweet thunders

Ideas would be most appreciated if you run the muffler you are suggesting...

[ib4200]

Its a three inch X with a pair of sweet thunders




you mean the 3 inch diameter pipes with crap in them that weigh 40 pounds each? some mufflers cant be that bad

[LTb1ow]

What?

[KirkEvil]

What?

I think that was an attempt to make fun of your current system, then agree that you should put in real mufflers.

[ib4200]

what dont you understand? kirk is right

apperently my borla system sounds like an older carbed car, the hooker mufflers sound pretty nice too, depends what your looking for

[LTb1ow]

Ah ok.

Please keep the criticism constructive and refrain from posting if you do not have the muffler you are recommending.

kthanx

[HeadlessNorseman]

super 44s or dynomax ultraflows! then either turn outs or over the axle dump

[sweetbmxrider]

what dont you understand? kirk is right

apperently my borla system sounds like an older carbed car, the hooker mufflers sound pretty nice too, depends what your looking for

a muffler for the stock location won't work in this application.

[JerzLT1]

Pypes M-80 its a canister style muffler

[SuperSweet]

Im running sweet thunders...love them. But I'm LS so its not as loud at idle ;)

[FIcamaroRE92]

pypes violators sound sexy as hell .
