    GPR vs. XLT exhaust resonators

    I notice the GPR has a single resonator between the water box and exhaust outlet, while the XLT has a different style resonator and a small additional resonator as well. Is the XLT set up quieter? Dose the GPR set up have a benefit? Has anyone tried the GPR set up on the XLT? Perhaps I'll try just to see. The smaller resonator is of the "straight thru" design, could it possibly have any downside? Looks like it might reduce sound but no other effect.

    I believe the XLT waterbox has a smaller outlet size, not sure if its a restriction or not. Haven't studied the sound suppression differences.

    Yes, the XLT Waterbox does have a smaller outlet, but only by a fuzz, like 1/8 or so. I swapped in a GP1300R waterbox last fall and found that out, the stock connecting hose was pretty easy to convince to go on the box outlet, so no big deal. But I bet you are on the right track, I'll do some measuring, I bet the entire exhaust track is slightly larger.
