If you're in the market for a quality high-performance exhaust system, then you will be pleased with the HKS Racing Muffler. This is a single-exit exhaust system that is a direct replacement of your OEM exhaust system. It has been designed with smooth bends to reduce turbulence under acceleration which will improve initial throttle response and will add more horsepower and torque.

New gaskets and hardware will be included with this exhaust system, and exhaust hangers have been welded on the OEM locations so no further modifications to the body will be needed. The piping has been coated black for extra protection against rust and corrosion, while the muffler will come in a nice polished finish with a titanium finished tip.
