Recently bought 07 V Rod with slip - ons. 12 disc and regular end cap. I wear a full face helmet and the sound level for me is deafening. Earplugs help, but on an hour or so ride it gets real old. I took the end caps off, and that helped a little . . . by letting the sound project out to the rear of the bike instead of directing it through the disc and toward my head. Before I go to the trouble and expense of another type of pipe, I m wondering if there is some way to improve on the current setup. Different end caps? Baffleing ? Whatever ?
Thanks

PS Also wondering how long I can run without the end caps without remapping the A/F module without fear of damaging the engine ?
