Two Brothers S1R Black Series Exhaust System Yamaha FJ-09 / XSR900

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:

  • 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

fj09 rev rev
First of all going from the stock muffler and catalytic converter anything is a upgrade. The fj09 went from a whiny singer sewing machine to a fire breathing dragon, literally if you don't block off the AIS. The sound has a nice deep and rumble almost like a flowmaster ,but when you open the throttle she get very loud very quick. The nice thing about the exhaust is no highway drone I've put 10000 miles on her mostly 70 mph highway riding and I still have eardrums. Best purchase I made for the fj09 besides full givi luggage .

Great sound, easy to install, will need a PCV or reflash
Bought this to install on my Yamaha FJ-09, took about 30m to install. The pipe sounds great, backfires running lean. You will need a power commander V or an ECU reflash to smooth out the first few gears, the pipe will backfire and crackle a lot until you do this, as well as drive down your fuel efficiency.
