whats a cat back system and whats the diff between that and a muffler. if they are both desighned to make it sound louder then why not just get the muffler??? its cheaper and makes the car look nicer
a cat back system is a complete system that goes from catalytic converter to wherever you want it to exit and a muffler is just that a muffler not an exhaust system
Dolomite edit: Or diamond, if you include the slang meaning of rock!
