Need some help with this one.
I'm looking at replacing the stock cast iron manifolds, and found these headers for the gen 4 camaro, that are smog legal in California but im not sure if they will fit in the G body.
Maybe somebody here has tried and knows the answer.

i don't think those will fit. they are meant for caprice engine bays, which are wider. i think the left header will interfere with the brake booster. right header looks a lot like the camaro header i tried, the collector joint may hit the right lower control arm rear mount.

anyone else? i too would love to find a set to replace mine lt1 cast iron manifolds but want to keep the egr hook up.
