Header TO SLP LM1

[Camvill]

I installed my pacesetter headers but they dont fit up with my SLP LM1 what do i do??

[JW]

What y-pipe are you using... is there a size problem? What do you mean by they don't fit up?

JW :D

[camaro2you]

It should fit up just fine, are you using a pacesetter y?

[naSSty99ss]

are you using that S pipe that goes between the y pipe and the cat back, if i remember right, when i helped a friend do his headers on a lt1 you don't need to use that s pipe anymore. he had pacesetter y and lm1

[LTb1ow]

Yea if its setup for a stock Y pipe, my cat back was, you have to cut the S out of it and it should be a straight shot back from there.

[sweetbmxrider]

i have shorty pacesetters with their y-pipe. cat welded to that. s-pipe bolted to that. I-pipe clamped to that and so on.

[LTb1ow]

Thats the legal way of doing things though. With LTs things change.

[sweetbmxrider]

yeah i know. i like saving the environment one catalytic converter at a time :lol:

[LTb1ow]

Oh me too, I have TWO brand new ones on the car. Granted they are in the trunk, but that still counts right? :wink:

Do not, I mean DO NOT to headers and a LM1... you will hate yourself.

[LTb1ow]

Borlamouth is still raspy.

[sweetbmxrider]

i like my car, granted its shorties and its catted. i think it sounds great!

[JL8Jeff]

I ended up trimming one side(y-pipe or I-pipe) and then got a 3" junction pipe from Autozone or Pep Boys and some extra clamps. I had to do the same thing on my old 96 SS. I hate the 2-3/4" neckdown on the y-pipe so I cut it off completely to run full 3".

[LTb1ow]

Get a nice cat back like a B+B 8-)

[NJ Torque]

I have a magnaflow that I need to put on.

It was cool for a week, haha.

[JL8Jeff]

I wouldn't even want to start the car up with longtube headers and LM. :shock:

[LTb1ow]

Why not? Its not that horrible. Its like blaring more than anything.

[KirkEvil]

I have LTs and the borlamouth setup. It really isnt that bad, just a lot of hissing noise along with the rumble. Cabin noise at 70 mph is actually quieter than it was with just the LM or BM because the tone is deeper. I ran the setup with the TSP catted y, and now with the ORY. Catted sounded slightly better. The noise is tolerable to 3000 rpms then it changes from freight train to thunder storm.

i have the offroad pacesetter y pipe and it doesnt match up at all i guess ill have to jimmy rig it with some sort of clamps

In what way does it not match up though? Crawl underneath and shoot a few pics from different angles to show us....

[Camvill]

ill try and get some pics up but the y-pipe was too long at first so i disconnected the pipe above the rear axle to make the y pipe fit. After i connected the y pipe the pipe curving around the axle didnt match up.

[Tru2Chevy]

If the y was too long with the rest of the catback hanging correctly, then it needs to be cut down to the correct length. Unless it's really close, don't move the catback around to try and fit the why, because it's just gonna create headaches with fitment around your rear suspension.

[sweetbmxrider]

yaa that over axle pipe has minimal clearance. you want that right and do your finageling with the y pipe!

[Camvill]

i have to get a muffler its too loud what one do you guys recommend and what part of the exhaust should i put it on

[LTb1ow]

Oh come on, be a man.:wink: But if you must, with the borla muffler stuck in the pipes, the LM1 and LTs quiet down a lot.

[JL8Jeff]

The LM2 muffler/resonator should bolt right in. They pop up on Ebay from time to time.

[KirkEvil]

The most you can quiet it down is with either a borla xr-1 muffler or a Magnaflow bullet. I vote borla obviously, but know that no matter which resonator you put in there its still going to be very loud!

btw, you will have to cut about 3" off the intermediate pipe between the Y and resonator to fit a borla. The borla muffler is 20" long compared to the LM resonator's 16.5". Any you will have to either weld it in or get 3" band clamps because it is not a perfect slip fit.

[Camvill]

what do you guys thibnk about dynomax bullets

[bcgetfresh]

I went with the borla XR-1 which sounds nice. I like the deep tone. Im actually going to be buying a GMMG exhaust really soon if your interested in buying mine. ill shoot u a pm
