{"product_id":"supreme-sp-cat-back-exhaust-system","title":"Supreme SP Cat-Back Exhaust System","description":"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.\n\nConstructed 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.\n\nThis 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.","brand":"Greddy","offers":[{"title":"Default Title","offer_id":52688600957240,"sku":"GRE10118206","price":855.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664203570.webp?v=1784891679","url":"https:\/\/store.motormia.co\/products\/supreme-sp-cat-back-exhaust-system","provider":"MOTORMIA","version":"1.0","type":"link"}
