The Mirage Slip-On is a distinctive new exhaust system that brings you the sound and performance of a conventional slip-on while giving your R1 an innovative custom look. The Mirage works in conjunction with Yamaha's EX-UP valve technology to create a low profile appearance that blends in with the dynamic shape of the Yamaha R1. The system is fully hidden from behind and provides an unobstructed view of the rear tire and suspension. Whether you're looking for a finishing touch to your custom project or simply looking to upgrade your exhaust system, the Mirage will provide you with a stylish performance edge that's competitive with other conventional aftermarket systems.
