GReddy Supreme SP – HG (High Grade) is our premium stainless-steel cat-back exhaust for the (FK8) Civic Type R. Besides the looks of the HG’s fully polished stainless-steel mandrel-bent piping and unique, functional GReddy three tip configuration; extensive research and development has lead to this supreme exhaust system. Careful attention was placed on the Civic Type-R’s exhaust sound characteristics, when incorporating our purposeful, high-flow, tri-routing layout. The large 76mm (3”) diameter piping flows smoothly through a large mid-pipe resonator and then branches out to the high-flow 3” center SP muffler and the two side-mounted sound chambers, before exiting the GReddy triple exhaust tips.
