A 364 days later I want to resurrect this old thread. I see a lot of 370Z header installs but nothing in detail of the G. My mechanic snapped off one of the studs in the header to cat on the right side and now I have the car back. My cats nuts (haha) look like lumps of rust, that is how bad my Chicago 150k mile car is. I did the ATF/Acetone treatment but my car is beyond hope there. I was thinking of getting Megan headers (since the broken stud) I already have their reso test pipes and was thinking of removing both stock units and reinstall. Is there a manufacturer or another writeup? I am assuming my motor mounts are shot and will need replacing as well. I see that Stillen headers miss the steering issue but are $$$. Drilling the stud is not an option really.
