Hmm, maybe I'll reconsider my opinion of MAC, certianly I will do some more digging before I even get close to buying my Headers and H pipe. Anything that is made by humans can be made wrong, the trick is to keep the mistakes to a minimum. Also how they respond to quality problems is very important. When I put my cat back on, I had already cut my tailpipes off with a sawzall, if the system did not fit etc I would have been screwed
since this is my daily driver, food for thought eh
