I installed a yoshimura r77 exhaust and it was a tight fit next to the rear tire, but never touched. A few weeks later I hear it rubbing the tire when I was cleaning the chain, I pulled the pipe back off the tire and there was a tiny rub mark. The pipe/can had a gap between the tire and i rode again, came home and the tire was rubbing again. My question is any of you guys with the yoshimura R77 have an issue with it rubbing or could you tell me how close the pipe is to the tire? I'm wondering if my bracket isn't bent enough.
