The future is here in the form of the Two Brothers S1R Exhaust System. The business end of this exhaust features an aggressive and lightweight magnesium end cap with a non-stick teflon coating. The exhaust sleeve is made of a 33 million modulus grade carbon fiber making it strong without being overly brittle. Within the muffler body lies TBR’s spiral-wound perforated core technology that produces an exhaust note that Chuck Norris would be proud of.
The midpipe of the S1R is race proven and dyno tuned and is made of #304 chromium-nickel stainless steel. This particular steel is not only strong and lightweight but also turns a golden amber color after a few heat cycles giving it a distinctive character. Power improvements can be felt in both the mid and high rev-ranges while the dropped weight will improve acceleration.
Note: Muffler image is for reference only. Actual S1R muffler will vary slightly depending on your bike's make and model.
