The Two Brothers S1R Black Series Exhaust takes the state-of-the-art S1R design to the dark side with black billet aluminum inlets, stealthy TBR badges and Two Brother's signature carbon fiber weave. The S1R produces that deep and throaty sound that TBR is known for thanks to their spiral-wound perforated core technology. The rubber lined natural finished aluminum muffler clamps feature an aggressive angular design and cutouts to reduce weight. The mid-pipe is constructed from .035” thick 304 stainless steel. After a few heat cycles the 304 steel turns a golden amber color, the hallmark of quality stainless. Of course an exhaust can't be all show and no go, that is why the S1R exhaust is track tested and dyno tuned to offer the best performance package.
