THis one I can tell you from experience...stay away from the Pacesetter setup! Yes, I know it fits and it is cheap, but that is just it, it is cheap! I got one when I first got my car and it sounded horrible. It was way too loud and everyone complained that it sounded bad...like a pissed off bee! I yanked the pacesetter muffler and header off and installed a DC Sports header (flowed much better and the O2 sensor mounted in a much better place) and then had a custom exhaust system made. I got a Flowmaster 40 series Import muffler and custom twin 3" stainless tips and the car sounds great. As for the Borla, I have heard plenty of Borla exhaust systems, and if you can afford it, go for it, they sound awesome. 8)
