HKS Sport Exhaust Systems utilize a specific muffler design and piping diameter to reduce backpressure and increase exhaust flow for greater peak power and a broader torque band without sacrificing low-end torque. Exhaust piping is 60mm with stainless steel muffler and a 100mm tip. Designed for off-road use only (noise at 96db instead of 95db Cali. law).
