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 headers and midpipes of the S1R Exhaust System features race proven-and dyno tuned stepped exhaust pipes 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. The stepped design creates a vacuum effect that forces hot exhaust gases out at a higher rate compared to a single diameter pipe. Power improvements can be felt in both the mid and high rev-ranges while the dropped weight will improve both acceleration and cornering speed.
Note: Two Brothers badge on muffler is the minimal black and yellow logo. Image of muffler for reference only, actual muffler varies per make and model.
