I want to vouch the for d&d, i personally do not have that exhaust but a riding buddy has it and I think it sounds sweet. Like it was stated up above the pitch seemed a little higher, not like a weedwacker but just a little more 600 like. On the other hand if you want real loud im running some race cans with full exhaust they say NOT FOR STREET USE in big letters but i covered that up... They are very short and light and Definately felt power increase after the install. Going under overpasses sounds amazing, Not to add i got best sounding bike out of about 30 or so other riders on all different machines.
