DETAILS
HKS Sport Exhaust Systems are engineered to reduce backpressure and improve exhaust flow, resulting in increased peak power and a broader, more usable torque band. Each application is carefully designed with a specific muffler shape and internal configuration, along with an optimized piping diameter, to preserve low-end torque while maximizing high-RPM horsepower.
These exhaust systems are constructed from durable S409 stainless steel and feature black corrosion protection applied throughout the piping for long-term reliability. A 106mm polished exhaust tip provides a clean, aggressive finish, while the 75mm piping diameter supports improved flow without sacrificing drivability. All required gaskets and mounting hardware are included to ensure a straightforward installation.
