ok guys, i recently put a header on my 97 cx hatch and did away with the exhaust manifold and catylic converter, which for those who know were both directly connected unlike the ex models, now i have both o2 sensors in the header, and no cat. the car runs fine but sounds shitty at mid range (has an axle back exhaust). can someone tell me the best way to go about completing my aftermarket exhaust set up to get the most out of a d16y8, and have it run good and proper, but sound nice too? plz bump if you view and pm me if you can as it would help me faster. thanks
