I had these mounted on my 87 BMW R80 (38mm exhaust header pipes) before selling it. The Stay-In-Tune muffler set provides a warm sound with a bit more rasp than stock BMW mufflers offer.
Australian made of high quality stainless steel.
Excellent slip on muffler with end clamps included.
Compatible with BMW and many other makes of bikes with a 38mm exhaust header pipes .
