For the best performance and good sound that's mellow when cruising, the V&H Pro-pipe is in the top 3. If you want to keep the dual exhaust look, then you can get the false left pipe for that system.bc_hombre said:still at dealers and still time to decide....................classic turn downs vs ovals, i assume neither is unpleasant to listen to after 3-4 hours of highway cruising. oui? i mean, they are not too radical, but i have never driven with them for a long spell. which set barks better when you nail it? thanks, opie.
