I recently upgraded my exhaust to an SLP slip on. After about 25 miles with it I started hearing a chirping noise similar to the bearing going out on the primary clutch. After further investigation I learned that the exhaust itself was responsible for the chirp. I took it off and put the stock exhaust back on and I couldn’t hear the chirping anymore. I can’t tell if it’s the exhaust itself or if it’s vibrating something. Has anybody had similar experience with aftermarket exhaust? Any ideas where the potential chirping may be coming from?
