I wonder if 50% more boost really means 50% more exhaust. Maybe someone can chime in.

As stated though, there is practically no power to be had from the exhaust. If you want extra sound, just remove secondary cats and/or Resonator and you should be very happy.

Intake will yield pretty good results, just did mine last night. Haven't really gotten a chance to test it out yet. I would definitely at least get a 65mm pulley. You won't regret it. I say the 65mm because the 62mm will more than likely require some fuel mods. The 65mm will be an easy bolt on for an easy ~25whp.
