Hi all, I just signed up and wanted to introduce myself. I have a 110K all stock except for a K&N FIPK 96 mystic cobra. I want to do an exhaust catback upgrade here soon but I don't know which company performs the best. (I want the most hp out of a catback). Anyways, I'll be around asking as many questions as I can. My goal is to get at least 400 crank hp out of my all stock engine (no internal mods). Thanks again guys. And I look forward to meeting you'll!
