M4 has gone to great lengths to make sure their full system exhaust for the R3 is better than the competition. In fact, all YamahaR3Racing.com and NortonFab Motorsports team bikes feature M4 full system exhausts because they were the best exhausts we tested. Now, M4 Exhaust has stepped up their game once again with the Full Titanium WORKS exhaust system for the Yamaha R3. We tested this full titanium exhaust as soon as it was available and results were excellent. This is now our standard exhaust for all MotoAmerica Junior Cup Spec. builds as well as any customers looking for the best and lightest exhaust available.
The M4 Titanium WORKS full system exhaust weighs an incredible 15.5 lbs less than the stock system, weighing in at only 5 lbs for the complete system and includes a lightweight aluminum exhaust hanger bracket as well as the M18 O2 Sensor Bung Plug. That’s almost half the weight of the standard M4 Stainless Steel Full System!
The Titanium WORKS system also features optimized bends for maximum performance and better ground clearance than the standard stainless steel systems.
All M4 full system exhausts come with 18mm wide band O2 sensor bungs and also include reducers to fit 12mm narrow band O2 sensors such as the Yamaha R3 OEM sensor.
“M4 is already known for the exceptional performance of its standard R3 pipe. Now we are offering our racing customers an even better option with our full titanium “WORKS” system. Racers in lightweight classes are looking for every ounce of performance from their machines, so the M4 team decided to design and manufacture this trick exhaust….because we love racing!” -Kyle Martin, VP at M4 Performance Exhaust
