Product Description

This exhaust system by HKS has a cannon ball-shaped shell which usually has a lower silencer capacity than an oval-shaped shell, therefore to reduce the sound level, the pipe diameter is narrowed. A narrow pipe diameter also reduces the exhaust efficiency and increase the exhaust pressure.
HKS utilized original unique technology to maintain the exhaust capacity and sound level to meet the JASMA standard which is more severe than the regular safety standards. Inner structure of the silencer was redesigned so the unwanted low exhausts resonance was eliminated and the sound quality was improved.
