I gave much deserved rep for being the guinnea pig.
I have a question for focusboy, or anyone else. If I wanted high flow exhaust (this header and full 2.5" exhaust) what are some muffler brands/models to look at to keep the car fairly quiet. In a perfect world I'd like to have a full free flowing exhaust that is just as quiet as stock.
Also, has anyone tried (or have links to flow tests) of some of the high flow cat's sold by companies like Magnaflow? I'm curious if it is possible to have a aftermarket cat that still flows fairly well that would stay legal for some who need it. Of, if the whole high flow cat thing is just marketing crap.
