I searched for this problem but could not find it. I have a 2015 with a 1320 header & muffler (no cat), stock windshield, and baker wings. Yesterday I installed Baker windshield deflectors (on the top of the windshield, after we both got bees in the face). I loved the quiet, less air, etc. BUT, we both immediately noticed a lot of exhaust in the cockpit, at any speed. Anyone else have this problem and hopefully a cure? I really don't want a rear exhaust, no matter how careful I am there are some driveway and parking lot curbs it's almost impossible not to scrape a little.
