Hi Everyone, I currently have an AWE catback and otherwise my car is stock. I am going to be adding a downpipe and I was going to get the AWE downpipe because of the no CEL guarantee but it is too expensive. My main thing with the downpipe is sound, I want a more aggressive and louder sound. Basically want to know two things. Does anyone have an AWE catback with an aftermarket downpipe that sounds aggressive. The second thing is, for those of you running an aftermarket downpipe I know all about stage 1/2 and o2 sensor spacers, but does anyone have success with their downpipe not throwing a CEL with only the spacers and a stock tune? I'm going to get a tune down the road but really want to know who has had success with o2 sensor spacers and who has that aggressive sound I search for. Thanks so much.
