Two Brothers S1R Black Series Exhaust System Kawasaki Ninja 400

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.

All exhaust pipes of the S1R Black Series Exhaust Systems start life as .035" thin wall #304 stainless steel tubing. #304 stainless steel, a lightweight austenitic chromium-nickel stainless steel which has low thermal conductivity properties and is corrosion resistant, even in the harshest environments. TBR then took this versatile alloy and infused it with their stepped exhaust technology. The stepped header system forces the exhaust gases to travel through incrementally larger diameter exhaust pipes on its way to the muffler. This design creates a vacuum effect that forces hot exhaust gases out, allowing your engine breath better while simultaneously increasing horsepower, torque and throttle response.

Features:

  • Full system exhaust includes headers and slip-on
  • Aerospace high-temp carbon fiber
  • Stamped spring-fit inlet
  • Optional P1 and PX1 sound inserts available (sold separately)
  • Optional anodized bolts kits available (sold separately)
  • Made in USA

Note: Muffler image for reference only. Actual S1R Black Series muffler will vary slightly depending on your bike's make and model.
