Thanks for the advice... Since all of you seem to be in agreement about the performance issue, I think I'll avoid the dual exhaust. Granted, I think the dual carries a nicer look, but like you said, that's a thing for show cars.

So lets take a look at single tube exhausts. I was reading over a post earlier on the Tsudo Fireball, and a few people seemed to be really pleased with it. Any suggestions for a system that'll carry decent performance, provide a deep, clean sound, and carry a nice look. I'm not interested in the coffee-can size mufflers or anything that sounds like a dirtbike. Looking for something classy.

Again, thanks for the advice on avoiding the dual system.
