I don't really feel it's necessary these days with all the muffler options and crossover pipes. An X-pipe and good set of mufflers can be pretty quiet, especially if it has tailpipes.

My 9 second DartSport had 3.5"pipes, X-pipe, Magnaflow stainless race mufflers and the pipes exited on the side right in front of the rear tires.
People would tell me they thought I coasted into the staging lanes because they couldn't hear it.

My current mid 10 sec street car has 3" pipes, H-pipe, Jones stainless straight-through mufflers, and 2.5" tailpipes.
It is very quiet and I love the sound. But I do have electric cutouts for fun and track time. I haven't made a pass yet with the cutouts closed.
