Naturally Aspirated (NA)
Last week i put on my 4-2-1 DC header bolted on to a greddy TI-c catback which has like a 10inch resonator welded in it. The setup is way too loud for anyone's taste and so raspy from about 2800 to 4200 rpms. From what I've read on the forum, my best move would be too add a cat in the stock...
