Headers: JBA longtube Headers
Mid Pipes: O/R X or H-Pipe
Mufflers: Magnaflow or Borla Mufflers (nice mean bark) or you can go with the flowmaster setup which makes your car scream rather than bark.
I ditched the Flowmasters because my car kinda' had a cheap, tin can sound at low RPM's, but absolutely screamed at high RPM's. I went back to the Magnaflow set-up because it gave my car more of a 5.0 sound (deeper and more musclar tone).
