p.s there's also a place that makes power pullys for our 6v ill be getting them soon and let you know about the performance and the sound of the exhaust if i redo that!
Depends on the car...if your handle is what you have...just remove the AMG resonator (around $40-50 bucks) a simple job that can be done at any quality exhaust shop. Unless your looking for an exhaust system that will wake up your neighbors, this mod will give the exhaust a nice, deep growl. I am not sure on the base Crossfire exhaust setup if it has a resonator on or not on it.
Same deal with pulleys. Many shops now are carrying them (EvoSport, Kleemann, Renntech, etc.) for our engine (SLK32)...again though, not sure on the base non-supercharged V6's...
