Where is HP hurt the most in regards to the exhaust system: the cat.converter, or the muffler?
My real question is, is there really a performance increase if a High-Flow MUFFLER is put behind a stock cat.converter? I mean, what good is it to have a "hi-flow" muffler, if the flow is already decreased by the cat? Know whut I mean?
