New Arrow Exhaust Half Race Systems for Yamaha R1/R1M

RICHMOND, CA – June 15, 2016  – (Motor Sports Newswire) – SpeedMob is excited to announce the newest weapon in the Arrow Exhaust arsenal – Arrow half race systems for the Yamaha R1 and R1M.

These new half race systems are derived from the dominating R1 “EVO” with Race-Tech silencer and the thunderous “EVO-2” with Pro-Race silencer. The full race systems have been stacking up club level podiums and professional podiums nationally in Moto-America for Meen Motorsports Yamaha R1 pilot Josh Herrin and TOBC Racing Yamaha R1 pilot Danny Eslick.

Due to high demand for the Yamaha R1 full race systems, Arrow Exhaust’s R&D have created a new half race system to fit from the factory headers’ back, making it the perfect solution for those wanting Arrow styling and performance on a more limited budget.

Arrow engineers optimized the design of the new half race systems to work in conjunction with the factory headers to maximize the possible gains. The final result is an exhaust offering smooth linear power throughout the incredible Yamaha R1’s entire power range.

The new half race system will be offered with two silencer designs:

The first exhaust design utilizes the popular Race-Tech silencer and offers a Titanium link pipe and a Titanium silencer body with a Carbon Fiber end-cap. The Race-Tech silencer also offers the added benefit of an included dB-killer for additional sound level control.



The second exhaust design utilizes a Titanium link pipe and the ultra-light all Titanium Pro-Race silencer that has been developed and refined through Arrow Exhaust’s various MotoGP racing efforts.



Either of Arrow’s new half race systems will shave off important pounds, increase maximum power with smooth usable power gains, and offer a deep-throaty note to your Yamaha R1 beast.
