V-Twin Exhaust
A crucial component related to the output power of a motorcycle engine, or any engine for that matter, is the motorcycle exhaust system. The flow of motorcycle exhaust gasses is directly proportionate to the resulting power and performance.
For the greatest horsepower and torque gains, installation of both a performance motorcycle exhaust system and headers is recommended. Riders can even double the power gains afforded with new motorcycle exhausts by upgrading the two parts at the same time. Plus, most manufacturers make matching pipes and headers, providing a complete motorcycle exhaust system that has been engineered to maximize the power output.
One amenity of a performance motorcycle exhaust system is that it delivers serious power boosts while also improving the motorcycle engine's overall efficiency. A performance motorcycle exhaust allows the motor to breathe more easily, so it can work efficiently without having to gasp for air. Depending on riding habits, a fuel savings of around 1 - 2% can be expected.
When it comes to motorcycle exhaust pipe size, bigger does not necessarily mean better. Stock motorcycle exhaust systems often use exhaust piping that is too small, which causes restrictions and back pressure that causes losses in horsepower. On the other hand, if motorcycle exhaust pipes that are too large for the engine is employed, the motorcycle exhaust will not be able to scavenge properly, which will cause a loss of power and efficiency. Performance motorcycle exhaust systems are built for the exact year, make and model, so you get an optimally sized exhaust system.
