  • downpipe and cat questions

    Ok...if I get a 3"downpipe, can I get the "offroad use" only since I don't have to worry about emission testing on my car when it gets inspected? I plan to eliminate the cat, or will the car run like crap without it? Thanks.

    The car will run MUCH better without it .. free flowing exhaust is the key ingredient in making HP with a SVO.
