Supreme SP Cat-Back Exhaust System

The GReddy Supreme SP Cat-Back Exhaust System is engineered to enhance the performance and sound of the Scion FR-S (2012-2016) and Toyota 86 (2017+). This 3-piece system utilizes a unique, horizontally mounted muffler with a 3-section design. An internal "Y-pipe" directs exhaust gases through a center chamber for sound reduction, while also feeding into straight-through outer sections for improved flow. The system is finished with dual GReddy slant-cut, double-walled tips that fit into the factory bumper outlets. Constructed with 63.5mm (2.5") piping and a large, straight-through resonator in the mid-pipe, the Supreme SP is designed to tune out unwanted drone. It retains the factory catalytic converter and front pipe, and uses a factory-type "donut gasket" flange for compatibility with both earlier and later models, including the 2017 Toyota 86 manual transmission and 2017-2020 Subaru BRZ. This exhaust system offers a modest performance increase, with claims of +6 hp and +7.5 ft-lbs of torque, as measured on a stock vehicle. The system weighs 34.8 lbs, representing a slight weight savings over the stock exhaust. Sound levels are rated at L82 / R83 dB(a) @4500RPM according to SAE J1169 testing.
