Hey everyone. Someone in my area has A Gm performance extrude honed header for a 2.2 cobalt for sale. It's unused and has everything to install it. It's at 325 dollars which is kind of expensive but compared to the over 400 dollars it would normally cost it's a good deal. Just curious if it will fit my 03 cavalier and if they are any good. Any advice is appreciated. Chris

It will fit but from what ive read it wont offer much of a gain if any.

If you want somthing that is proven to give you gains and bolts right up go with the Bad Mab shorty header.

But most will recommend going with a pacesetter over both.

Thanks for the info. I didn't realize the Gm ones didn't make any power

They do but its minimal.

Its basically a stock manifold ported out. Nothing that cant be done with a dremel. I think I recall some cobalt guys saying they got better results with a dremel.
