I currently have the stock exhaust system on a 2000 Z and I am considering a different system. I like the fact that my car is quiet around town and on the interstate, but i do desire a deeper tone. Most people have suggested either a Dynomax Super Turbo, Ultra Flow, or an SLP system. I want minimal drone and relatively stock volume at speed (65-80 mph). Any thoughts as to which is the best?

 

From what you describe the dual/dual will fit your needs best. Next to that I think the B&B would be good, as well as the Corsa.
