Great gain in performance, but did add a little more noise from exhaust.

Great product except the knuckle on the steering hits one of the pipes. I had to bend the pipe to make room for the knuckle and avoid wear and tear which would eventually wear a hole in the pipe and create an exhaust leak. There's no way to know until the motor is in where the knuckle makes contact with the pipe. I hope the manufacturer will make this adjustment going forward.
