I know that Kooldino is selling his racing beat exhaust (obviously used) but you could get one from him and save some cash. I too would be willing to save mine. I have yet to take it off, but I need to, so this would at least motivate me to finish my exhaust system.
My understanding is that it will fit a sedan fine, but it will not fit the P5 without some modification. The sedan is slightly longer than the P5, so the tailpipe would need to be shortened on a P5.
If you're interested in the used, PM Kooldino or myself. I have no idea what he's asking, but I'm flexible.
