Two Brothers S1R Black Series Race Exhaust Systems

Not Yet Reviewed

Two Brothers S1R Black Series Race exhaust systems are designed to surpass what is offered on the market. These systems are engineered to complement the quality and performance of today's motorcycles. They offer all the same great features and sound of the standard TBR S1R systems, but also feature Black Series mufflers with anodized black trim at each end and a black/gray Two Brothers logo. Just as with the original S1R systems, the Black Series is available with aluminum or carbon fiber mufflers. Order the system recommended for your bike.
