Two Brothers S1R Black Series Slip-On Exhaust Honda CBR1000RR / SP / SP2

The Two Brothers S1R Black Series Exhaust is a state-of-the-art product from Two Brothers Racing. It features carbon fiber highlighted by a natural finished aluminum outlet and stamped spring-mounted inlet for ultimate durability. All of TBR’s carbon fiber parts are made with a high temp aerospace grade epoxy resin. The carbon fabric is made with a 33 million modulus carbon tow then impregnated with the high temperature resin under very tight tolerances. The mid-pipe of the S1R Black Series is constructed from .035” thick #304 chromium-nickel stainless steel. After a few heat cycles the 304 steel turns a golden amber color, the hallmark of quality stainless. The exhaust note of can be described as a deep a thunderous roar thanks to TBR’s spiral-wound perforated core technology. Each of these components has been track tested and dyno tuned to offer the best performance package.
