Chevy Cobalt Performance 4-1 Header (2.0L / 2.4L)

[Chester]

Yes that would be greatly appreciated and someone mentioned on here a while back that all you have to do to make an aftermarket header compatible with the Secondary Air Injection system is drill a hole and add a bung for the tube where the old header had one

Ok I got word that the headers are NOT compatible with the SAI .. However, they are working on one that is .. I will post up when their SAI compatible one is available

if it fits a 2.0l it will fit the 2.2l considering its the same block. i cant see why there would be any difference

X2...the vibrant header, DC Sport header, and Weapon R header fit the 2.0, 2.2, and 2.4.

Got a review from a customer today

Summary: For the money it is worth it. The positive aspects of it out weight the negative.
Pro's: Header really helps the engine breathe better and it helps throttle response time. Bolts on easy and fast
Con's: Have to really over torque at the manifold or it will leak on cold starts. The coating flakes off after the first time you drive it.
