Review on Enhance Your Ride with kemimoto Motorcycle Universal Exhaust Slip On Silencers & Mufflers – Compatible with Grom ATV Dirt Bike Street Bike Scooter, 38mm to 51mm Exhaust Pipe Diameter by Jeremiah Vishwasrao

This is a clone of the sc Projects exhaust but the quality is good. You can't beat him for $33. The fitment wasn't possible as the midpipe and exhaust were the same size, I had to go to a muffler shop and ask them to widen the exhaust a bit so I could fit the midpipe. The muffler shop didn't charge me as they expanded it in less than a minute. It's a cool exhaust once installed. I haven't tried it with a silencer, no sound. Great addition to my 2014 cb1100.
