Product Description

The HKS 3306-RA072 is an inner muffler silencer insert sized for a 94mm HKS Hi-Power exhaust tip, designed to quiet the exhaust for daily street driving while remaining easy to remove for track days or spirited drives when full volume is wanted. Made from SUS304 stainless steel, it slides into the tip section and is secured with the included M6 hardware.

As the same type of unit found in HKS's own factory bolt-on exhaust systems, this silencer is built to the same quality standard as the mufflers it's designed to pair with. It fits any HKS exhaust with a matching tip diameter, with the exception of Carbon-Ti mufflers (except part #3112-EX006, which is compatible).
