Header DP combo
Header DP combo
trying to find a good exhaust mani and dp setup....
im thinking this : zzp's 2.5in dp bolt in
Cobalt & Ion ---> ZZ Performance
with : Pacesetter Polished Armor Coat Header or the painted plack one
Pacesetter Polished Armor Coat Header 4-1 Style Chevrolet Cobalt & Saturn Redline 2.0L SC 2005-08 - Exhaust & Header - Turbo Tech Racing, LLC
seems fairly cheap to open the most restictive part of the exhaust system.. jw if any ones ran this combo? did it bolt up good? and to the stock cat back? and howd it sound threw the stock muffler?
thanks

No one can really say what the gains would be. ZZP is doing some testing on theirs right now. You should wait and see what they come up with.
Most do say the long tube makes the exhaust system quieter though.

2.75"-3.00" is the best downpipe size for the lsj (depending on mods/power level).
If you are dead set on getting a header I would wait for testing to be completed on ZZP's long tube.
Fyi a catless downpipe will give you fart can sounds. Stick with a catted downpipe. The possible 1-5hp gain from a catless downpipe is not worth the crappy sound they produce.

I've heard that 2, but I find it hard to believe. Why leave the stock catback if you are going to modify the exhaust system? You do know that the inlet of the stock resonator is only 2 1/16" right? Hardly ideal when looking for maximum gains.

Yeah, most people think that they can just replace the 2.25" section over the rear axle on the stock exhaust and "bam" have a true 2.50" catback. I was shocked when I removed my stock exhaust and saw the tiny little inlet at the resonator.
