Has anyone installed one of the GMPP Extruded Honed Exhaust manifolds on their 2.2 and if so did you have to make any modifications?

Bump for Tom's answer.

TMK the LSJ manifold slaps right in and this is a replacement for the LSJ manifold. It follows, then, that this should slap right in as well. Some 2.2's I know have done it and I'm not aware of any modifications that were necessary.

direct swap, no fab required

As long as your cobalt doesnt have EGR

Thank you guys for the info.

-A day late....the GMPP extrude honed manifold is a direct replacement for the 2.2L as long as the 2.2L does NOT have the Secondary Air Injection (AIR) system. If the 2.2L does not have the AIR system they just need the gaskets to install it.

If they have a second smaller black tube coming out of the top of the air filter box they have the AIR system and the extrude honed exhaust manifold will not work.

what about the downpipe? should it be ok? unless gm has a performance downpipe? or should we really look for an aftermarket one.

all the cobalt headers/downpipes should fit any of the 3 engines..
