SC Project S1 vs SC1-R?
Anyone out there with an M1200R 2016-2019 who has experience with either of these two exhausts? I am considering one or the other to pair with "Rapid Bike EVO auto tuning mod". I realize the S1 is louder. However, I've heard due to lack of back pressure (e.g. no CAT, nor baffle) it performs oddly at idle. Any insight would be appreciated. Thanks.
