I am trying to find out what cat back exhaust system works best. My car is a 2000 Z28 /A4. I just got back from Florida where I ran a best of 13.66 @ 103.5 MPH. I want the car to sound good at idle and at speed. I have looked at the load mouth, Mufflex , and the Flowmaster systems. My biggest concerns is as I build the car is that I don't want to have to replace the exhaust system again. Please let me know if you have any ideas.
Thanks, Will
