Review on PACEWALKER Chrome Motorcycles Slash Cut Exhaust Muffler Pipe for 1.375", 1.5", 1.625", and 1.75" Choppers and Cafe Racers - Loud and Ideal for Suzuki 650 (1 piece) by Kyle Omaha

I put them on my 2016 Indian Scout 60. You sound amazing! However, installation was tricky as the included zip ties were junk and the input ends had to be opened up a bit. It took a bit of "tough love" to open them wide enough to fit the bike and put my stock clamps on top. They're the right size, but there were burrs on the inside of the end of the clip that wouldn't come off. Took them off with a dremel and they fit perfectly. Hard as a rock. I love these whistles!
