for under 3 bills your best bet would be a performance muffler, resonator(s) and custom 2.25'' pipes, but be ready for the droning and headaches it will cause on long drives. almost all of the custom exhausts ive heard are loud as **** even w/ resonators. just another bill or so you can get a Apexi WS brand new. i picked mine up used for 2 bills and i love it.
