I'm going to go with some QTP LT headers but they offer them in 1 3/4 and 1 7/8. Which one to go with??

Also I'm leaning towards the race headers cause I Live in SC and we have no emissions testings. But if I remember right the 02 LS1's didn't have egr so it should just be a straight install. Anything else I need to know??

 

i am pretty sure you would set a code by having no AIR provisions on it, but that can be erased with ls1 edit

 

QTP headers, get what you can afford, man!!
I think the 1 7/8 have slightly bigger tubes. Me personally, I'd get the 1 7/8's with the high velocity collector. Thats what I'm planning on getting after the winter.

 

Yeah I thought about the velocity collector but it's like $500 on top of the $800 header

So the 1 7/8 would serve me better then?? is there any fitment issues v/s the 1 3/4??

Thanks

 

Thats actually pretty cheap for the high velocity collector. Its 800 just for it from borla. You shouldnt have a fitment issue with the 1 7/8. Its pretty much the same size.

 

Rice, 1 7/8" would be overkill for your car, same with the merge collectors. IMO, go with the 1 3/4" w/o the merge collectors, unless you just want to spend a lot of money or you're planning on H/C in the future.

You can go with the race style or emissions style...but with the emissions style, you're paying $75 for just the AIR provisions. I dunno if that's worth it to you or not.


Trust me though, for a bolt-on car, 1 3/4" is more than adequate. You can get the merge collectors if you want but they'll probably only give you about 2-3 more ponies over the standard collectors. With H/C, they might make a noticable difference but with stock heads and stock cam...probably not much, if any. They're just meant for people looking to sqeeze every last bit of power they can get out of their car.

 

Well, thats true.. i'm one of those "get every last bit of power i can sqeeze out of my car" kinda people, so thats why i recommended the high velocity and the bigger tubes. I just think of it as, get the best you can afford, otherwise you will have something that you paid a lot of money, but could have spent just a little extra and got the absolute best available. 96flz is right though.. it probably would be overkill, unless you were planning any further mods to the car in the future, like a cam, or heads/cam combo. I've just regreted buying many things and having not gone for the model just above when I could have. For all intents and purposes, the pacesetter headers would probably give the same horsepower results as the QTP's if you just go with the regular style. I would think that the only thing you gain with the QTP's is the stainless steel factor. How long are you going to have the car anyway? if only for 2 years, buy the pacesetter's and save the money. i'm seriously considering that route myself.

 

Well since it's an 02 and they aren't making any more I plan on keeping it for a good while.

I just found out today when having my sfc's installed that it's already got MAC Mid length, MAC y-pipe w/ high flow cats and O2 sims on it going to a Corsa Cat back !!!

I'm thinking now that replacing any of this would be a waste since not a whole lot of ponies for the $$ spent.

I plan on getting a Patriot Performance H/C from Texas Speed hopefully by summer.

Will my current set up suffice??? Not a race car just trying to make a kick a$$ street car.

Thanks.

 

Can't believe you didn't notice that before. That's gotta be a real kick in the ***.

Either way, I'd look into replacing the MAC Y-pipe, or at least the converters. I've heard bad things about the flow of their cats. An ORP (or just getting someone to chop them off and weld in straight pipes, since you don't have emissons) shouldn't cost too much.

 

Well I looked at them when I changed the oil and I thought they didn't look stock but I didn't know. I just got the car 11/3/03.

I was going to go with QTP LT but now that money can go to a H/C setup. Will my setup work with a H/C ??

I think the car is strong as it is, never been dynoed or to track (yet) but I'd rather not cut it or put a new one in just yet. Seems like the $$ to performance ratio would not be good enough to justify it.

 

Man, thats sweet. I'd stick with what you've got! have you thought about getting an electric cutout?! those are real cheap.
Your setup will work with h/c combo, you'd probably see like 12-15 more horsepower from longtubes with the h/c, but hey, its not worth the money, since you already have a decent setup.

 

Yeah I didn't think the $1300 for LT was worth the little gain in HP.

So now definately gonna get a Qtec cutout

 

hey guys quick question are kooks headers stainless stell? Living in the Northeast I plan on buying a stainless steel header due to salt and **** on the road don't want any corrosion also idk how well ceramic coating will hold up, and how long. I know QTP and SLP are stainless. Just wanted to ask.
