For obnoxious and raspy, I always like 2 1/2 inch plated fence posts from Lowes. Cheap, plated tip, and will wake the dead......

You can achieve almost the same sound as a straight pipe by eliminating the resonater and uses one of the longer Cherry Bomb or Thrush glass packs. The longer the glasspack, the throatier the sound.

You do need a bit of back pressure in the system so going straight open from the header back is not a good idea.

Also, removing the cat will throw lot'* of codes and raise hell with your tune unless you can make changes to the PCM.

Take the resonator out and replace with just a straight pipe or a cherry bomb like Venom suggested.

Lose the muffler to. Put the glasspack where the resonater was and then the straight pipe.

Cherry Bomb Exhaust :: High Performance Exhaust Systems, Cat-Back Systems, Mufflers and Glasspacks :: Disturbing the Peace Since 1968 check that site out. Cherry Bombs or Glasspacks are one in the same.
