2003 BMW R1150r Roadster Custom Exhaust build and sound test. Stock muffler was removed, catalytic converter opened up, catalyst removed, converter closed back up and added a tip. The result is a very modest sound volume with a sleek look. it was also a weight savings of 12 pounds overall, muffler was 12 pounds, and the catalyst was 1 lb.
