C went back to 1.75. Installed them yesterday for her. Little sound quality or loudness difference. They all get a little louder with age as the baffle material will erode in time. You can also ask Jamie to send you the German baffle material for an extra 30 bucks. It lasts many times longer than the stock stuff.

The 1.75 give a little more restriction thus you will have a little better throttle response in low to mid range and less of a chance of decel pop.

If you change your mind after getting the 1.75's then come over and we can slip the 2.0's from C's bike into yours. They have less than 1000 miles on them. I've got them put up in the Hawg Pen in the Rush box the others came in.
