Help me find an ex system

[project89]

i have to get rid of the flowmaster on the car its killing me on the top end,
im looking for something else to put on the car and so far alls i can come up with is a borla or edelbrock muffler.what other options do i have
the only other thing that has been suggested to me would be an import style stright threw muffler,which i really dont want to do,

btw dosent need to retain the factory dual tailpipes
chambered mufflers are a no go chamberd muffler+ turbo = not good

[90FormulaWS6]

glasspack?

[project89]

sounds like ass/to loud

[Ian]

spintech

[ar0ck]

stock muffler w/ cut-out

[enRo]

:stupid: Or straightpipes all the way to the back

[Slow Z]

dynomax ultra-flo ...no brainer.

[JL8Jeff]

I have a Dnomax Ultraflo 3" inlet dual 2-1/2" outlet for sale if you're interested. $80 and it's brand new. This sucker is pretty much a straight through that is listed at 1200+ cfm.

Another vote for Spintech here!

[project89]

i like the way spintech sounds but arent they a chambered muffler liek the flowmasters?

[jrsfast84]

My friend Barry is selling his motor in his street car, he's Mufflex's 4" back to the rear w/Spintech w/ dual 2-1/2" tails on it,w/ no cats. I'll ask him if he would sell it.

not quite. It has coils inside that absorb the sound instead of chambers and baffles.

The Banks Power Pack system I had on my 82 was one of the best sounding exhausts I ever heard. But the dynomax muffler I replaced the banks muffer (rusted out) with sounded real good too.

dynomax doesnt sound to good, what muffler was it?

I don't see why he wouldn't, i'll pm you. JR1.

Dunno. It was whatever Dynomax muffler fit my Banks pipes nicely. :) 3” in, dual 2” (or maybe 2.5” – I forget) out same side. I'm just saying in generally I like the Dynomax sound - not too loud - but by all reports I read 'back in the day' they still flowed as well as noisier ones. And it wasn't silent by any means.

[project89]

thnx for the suggestions guys,im either gonna go with the spintech 3 inch in and single 3 out,or the dynomax.any idea which one would be quieter?

I have dual oval 4" w/ Spintech race mufflers and there very quiet with 15.1 comp. and it was done by Mufflex which did a great job.JR1.

[project89]

4 inch inlet is way to big for a 6 cyl

[Ian]

A kid I went to high school with had a spintech cat-back on his 2000 SS and it was nice and quiet idling and while cruising, but when he got on it it got a little louder. I just really like those mufflers because they dont sound like anything else.

[Savage_Messiah]

Magnaflow 3"?

[Frosty]

SLP two on the left. It's great if you can get past the looks. It flows GREAT and sounds good at WOT.

[Ian]

:stupid:

thats what I had on my GTA.

[Frosty]

So did I and I loved it.

[BonzoHansen]

2 on the left rules. Go not show.

[jrsfast84]

if i had your v-6 combo 3" or 3 1/2" would do the job, call Mufflex there very good and reasonable.JR1.

[project89]

yeah the biggest down pipe i can fit on the car is 3 inch,so i see no benifit in running 3 inch halfway to the back and switchng to a larger pipe,as far as getting ti installed i have a tubing bender,and everything i need to make my own pipes,though im gonna redo the ex system with all madrel bends and make it piece by piece,im still unsure about the spintechs i do love the way they sound.but they are sorta chambered i quess,so i may just go with the dynomax,i fogot about magnaflow.and the one kasey ha son his car sounds pretty dam good.though my last option.is gonna be to put a bullet muffler in the stock cats location and run no muffler.

anyone ever heard a moroso spiral flow muffler? looks like something that may keep the car quiet and not hurt flow to much

[Ian]

why are you so against chambered mufflers?

[project89]

im not against chambered mufflers at all.its that on a turbo charged car they create to much back preasure in the ex system.generally u want the least bit posable with a turbo.thats why most guys run like a 2-3 ft down pipe with no muffler.but this being a street/strip car has to have one. i already tried to run no muffler it was way to friggen loud

[Ian]

if you read the testimonials on spintechs website, you'd see that a lot of guys actually picked up some HP when they went from open pipes to spintechs.

[BonzoHansen]

“…so I see no benefit in running 3 inch halfway to the back and switching to a larger pipe…”. I think you are right – the exhaust gasses cool as they flow down the system – becoming less dense. So I see no benefit in larger down stream pipes. I bet slightly smaller pipes would have zero impact.

thats not quite true. when something cools off, it becomes more dense because the molecules slow down and and have to be closer to eachother to stay bonded. However that also means it contracts effectively taking up less room.

[NJLT1SS]

As for muffles, I would go with Borla, Dynomax Ultraflows, or Magnaflow.

[project89]

i took a better look at the spintech stuff and the way they are designed dosent look liek it would create the backpreasure the flowmaster does so im gonna give them a shot.more so just cause they have a really nice sound compared to anything else.It looks liek im gonna go with 2 spintechs.im gonna split the pipe were it comes over the rear.the spintechs fit perfectly on each side,im hoping the dual mufflers will keep things nice an quiet but still sound good.
though if that turns out to be to much of a pain in the ass im just gonna get a spintech single in and dual out and run 2 tail pipes out the drivers side.
