Description

Yoshimura has a long history of claiming championships on and off the track. With cutting edge design and manufacturing technology combined with experiences gained from their sponsored racing efforts, Yoshimura has become the leading manufacturer of exhaust canisters and full racing systems. Their expansive R&D department is dedicated to developing the best parts manufactured from high quality materials with extremely strict standards. This uncompromising attitude has brought them podium titles time after time. The Street Series AT2 slip-on exhaust for the Kawasaki ZX-4RR / ZX-4R is no exception to Yoshimura's rules. This lightweight and gorgeous exhaust produces a subtle yet distinctive sound that is unmistakably Yoshimura. The street-legal slip-on features Yoshimura's exclusive Works finish, meaning it has a media treated satin finish that produces uniform heat coloration and increased durability against scratches, stains, or fatigue. The AT2 slip-on exhaust is the result of years of effort and brought to life by the most advanced technologies in manufacturing. Its air flow has been optimized to provide maximum performance gains while remaining street-legal, giving you a little extra boost on the street when compared to Kawasaki's stock setup. The canister's unique and aggressive design gives the bike more ground clearance while also being optimized for durability and easy service.

The video made the install a breeze, I didn’t have to remove the fairings and literally didn’t need a single tool, hyperflash is gone on both lights, so much better than old resistors
