Muzzy Exhaust baffle noise after removal
I have this setup on a 2004 VTX 1800C. I got the baffle out, took all the fiberglass off and reinstalled the metal baffle and endcap. Still wanting a bit more loudness I took it out and cut the baffle down to the support washer that is welded to the baffle in the middle. Now I have a rattle on acceleration and deceleration. I'm thinking the washer is hitting the inside off the pipe and I should cut it off as well. I tried just the endcap alone but had a strange whistling noise on deceleration. Do you know what caused the whistling noise?
