We offer an oem exhaust modification service for the Aprilia RS660 and Tuono 660. This is NOT exhaust coring. We strategically modify the internal chambers of the oem muffler to increase flow and sound. We offer 2 options that retain the catalytic converter, and one option that removes it, similar to a race exhaust.
We offer exhaust shield coating as well as exhaust tip mesh grill inserts.

Dyno charts will be shared over the next few weeks. We will be sharing dyno info for sport/sport plus as Is with no ecu flash or upmap, and then sport plus with up map, as well as race with up map. We want to make it a proper option for customers and provide as much information as possible.
