Hey guys I wasnt sure if u guys knew who makes one of the best header/downpipe for our car for the money...yes i know already about the C/A..but i was thinking how is the gm one and others..also here is a thread on how my car is coming along..if uwanna hear how the injen cai and gmpp exhaust

The CA header will out flow the GMPP manifold basicly due to its design. As for DP I'd also say CA has well know well documented parts. Don't go past 2.5 inch tho as its a waste and you'll kill the lower end torque.

 

CA header/downpipe is the best by far for the money. I've had my CA header/XTC 2.5" de-cat downpipe in since November '06 and no problems thusfar.

If your willing to spend a bit more, might wanna check out the ZZP mid-length combo.

 

i mean dont get me wrong..i know the c/a stuff.used to go down to the shop all the time..its just i dont want it on my car..the locals have really gone away from them..i even tried emailin kenny about my car several months ago..never got a email..so i rather give i guess someone else the business.

terry check out those vids i put up

i mean if u listen to the vids..i like how the car sounds..just want it not to get that much louder

 

That bitch scoots! You ever get that tune to work right? I miss mine but I don't miss the CEL.

 

bro it works awesome.

i just want to make the car a lil less intake on the top end..u hear that the most uptop in the high rpm's..but yeah man the tune is kickin some ass.gonna log it more on thursday..but like i said..i dont want it that much louder..just a lil more exhaust tone up high if i can get it like that

 

Your an automatic right?

 

yeah...y cudnt tell?

 

No sound on the laptop so no not really. If your interested once you get this new mapping done and IF it works I'm willing to pay you for a copy of the tune.

 

haha the shifting is really tight. yeah man def will help u out man.

 

How about the Vibrant Header/Downpipe/highflow cat combo It is a really nice kit.

 

illmatic u got a tranny tuned?

 

GMP manifold and ZZP Downpipe is a good combo. Works for me and I have a SS/SC

 

+1 on that!

 

ZZP ALL THE WAY. What's it at now 369.99? And they just recently made it BETTER than it already was and I have never heard of any problems with one and it gives good gains.

 

Ive got a ZZP shorty and its BA, excellent quality!!

I had a ZZP midlegth header & downpipe combo also, again B.A. and excellent quality...

 

yeah my whole car is tuned..yeah the tranny tune is kick ass. its shifts awesome and real tight...u can def hear it..hahaha

 

just need to work on getting it to shift a little quicker and she's all good. logged it last night and everything looked peachy (lol).
Car definitely boogies for an NA 4 banger. But then we went for a spin in my car... and well... sean will tell you the rest lol.

 

dont get me wrong...the shifting is pretty good..just have to work it in from 2nd to 3rd and havent got it up to 117 where it shud shift to 4th..yes 4speed auto..lol. and yes pauls car is nuts..turbo 2.0 cobalt..no traction in the cold ass weather..but god damn.

 

i need a tranny tune...

 

u auto man?

 

I would go with the ZZPerformance mid length as it can be built for a N/A engine. 1.5" primaries with a 2.5" DP and flange with a cat. Just by the time you order it the right way your looking at $590, not much cheaper than the Vibrant.
Nice thing about the Vibrant is though, it is all Stainless Steel. Vibrant needs to publish more info on what this set up is as I have never seen anyone state what the primaries size are or the DP and flange size are.

 

Vibrant= 3" flange and 3" downpipe = too big for a 2.4SS IMO.

I'll leave the 3" exhaust components to the 2.0SS/SC guys. Typically, 3" is overkill for any 4-cyl w/o boost, unless its a fully built all motor 4-cyl.

 

I wouldn't even upgrade to 3" if it was a stock SS/SC. IMO you upgrade to 3" once you get closer to 300whp.

 

Agreed. 2.5" is plenty enough for our cars.
