For the more track minded enthusiasts where weight, sound and price point all are highly desired metrics, the APR Valveless system is the desired configuration. In this configuration the axle back portion of the exhaust has the mufflers and valves removed. Weight drops considerably and the system becomes more aggressive. The system is louder and more aggressive, but thanks to the center Helmholtz chamber, drone is reduced, giving a more pleasant, yet aggressive driving experience. However, when upgrading other exhaust components, the system transforms and becomes unapologetically raw with maximum aggression - A true track enthusiast's dream.
