2007 XL1200C.Have se street performer slip ons. Wanting to install a full system. Sound is o.k. from se with cycle shack baffles but not quite what I would like. Like the sound and fit of the V&H straightshots part # 17821, but don't want to lose any performance or waste $. Have a se stage 1 air cleaner and tune with tts mastertune. Any input appreciated.
