Welcome! Everyone has their own opinions when it comes to exhausts on these cars. Some will tell you to stay stock, some will tell you borla, magnaflow or slp, etc. Others will tell you an exhaust spinner (turbo) is best. The general consensus is get rid of that restrictive u-bend where the front o2 is plugged into, keep some kind of resonator in the mid-pipe and the rest depends on how loud you want it and how far your looking to mod your car. If you let us know we can be of more assistance. Also a search on youtube will yield plenty of videos with all kinds of setups on our cars
