I read somewhere that a 4th gen exhaust will bolt up to the h22 header. What I want to get is a 4-2-1 header and then a decent cat-back exhaust, and I want them to bolt up because I'm tired of heading to the shop to weld up an exhaust leak every so often. I live in a small town were no one knows how to weld apparently. Anyway...just wanted some clarification before I went ahead with this. Thanks guys!
