i just want to know what people think are the best headers. shorty mid or longtube. i know people with mid and lt and they are very happy. they claim long tubes required alot of fabrication, modificantion, and customization., mid's ive heard bolt nicer with the y pipe to the cat. just want some input










thanks craig

 

Longtubes I say pacesetters
Mids go for mac's
shortys SLP

If you are getting rid of your cats i say go with the longtubes.

 

longtubes outperform shorties hands down. most should be bolt on applications. i suggest replacing your motor mounts while the manifolds are off to keep the engine from moving too much under load. this will eliminate most rubbing or banging that is commonly associated with LTs.

mids are a good compromise, almost the same power as LTs but without the clearance issues

 

I say longtubes, install isn't really any harder. Clearance issues...I don't think you will have any if you get new motor mounts at the same time. Plug access is great as well..mine didn't require any customizing, or extra fabrication.

 

Longtubes hands down. I went with the pacesetters and a custom Y-pipe back to a flowmaster 80 series. It sounds great. My pacesetters knock a little bit, but it's nothing too terrible. I guess motor mounts would've helped that? YEAH THANKS FOR TELLING ME NOW GUYS. Oh well. Get longtubes. You'll be happier in life. Period.

 

Jet Hot Longtubes & y-pipe !

 

Lts, unless your laws say otherwise. Someone else can answer this, but I thought that Fed laws prevent you from changing the position or number of cats. If this is the case, you would be pushing it to install headers that require to move or delete the cats. JMHO

 

not trying to steal your thread, but do you guys recomend new motor mounts for adding mids, or just long tubes? and how hard is it to change them?

 

definitly a consideration. I went with smog legal shortys, only because I want no hassles on a street legal car, (smogging it, selling later, laws could change, etc.)

If your sure it will never be an issue, go for it. I live next door to CA, and all their idocy rubs off on NV.

 

Ya know what, i would recomend motor mounts with ANY headers. The reason is, you got the manifolds off and you can get to the mounts real easily..you might as well throw some poly mounts in because sooner or later you will need new mounts...and once you have headers on its a bitch to do. If the manifolds are out its like maybe a 30 minute job.

I had the SLP shorties and a Random dual cat ypipe before putting on Lts.
It all depends on what you have to pass for emissions in your state.
If it's only an OBDII scan then you with a friendly mechanic you can run LTs.
The LTs sound better but don't make that much more power than my previous shorties and random pipe, maybe 5-6 hp. If you want to just bolt it on then I'd go with mids.

 

that's what I run. The Y pipe is critical as the factory one bites.

 

Ya the factory pipe sucks.
That's why some people only get 10 hp out of the shorties and give them a bad rap.
It's restrictive and has an almost unpleasant reverb coming off the throttle because of the different distance of the coffee can cat vs the pass side one.
The Random pipe probably adds 10 hp out of the 20 or so with the SLP shorties.It'a a great combination and sounds very balanced.
The shortie header bolts can be a pain, especially the passenger rear. Mine came loose a few times.
TPiS LTs are the only ones that use regular manifold style 3/8 by 3" bolts which are all easy to get to.
They've never come loose.
However Kooks were not available as I would probably buy them as they're stainless steel and about the same high end price as TPiS (800.00) which are mild steel.
Love the big bolts though. That was what sold me on them at the time I was shopping for LTs. I had to weld in my own emissions fittings, but that wasn't too much trouble. They're also slip fit like the pacesetters and have excellent ground clearance.
Pacesetters seem to be a very good deal for the money and have ground clearance similar to the TPiS.

 

Because I wanted to stay emissions legal, I really like my AS&M midlengths. The sound is really nice with the high flow cats.
