The extended sedan version has similar features to our coupe counterpart, including high flow with a tuned exhaust note. The system produces the distinctive GReddy deep exhaust grumble while driving aggressively at wide-open throttle. This three-piece, cat-back exhaust expands to a large 3\" (76mm) forward-mid pipe and mid pipe that split to two polished, straight-through SP oval mufflers and dual center-exit dual-wall GReddy tips to improve the performance of the turbocharged 1.5L engine. Our system bolts to the factory exhaust system at the flange behind the engine\/transmission. The sedan version has a slightly more aggressive tip angle and the muffler combination is a better compliment to the Si sedan’s sporty, but wide rear bumper tip opening. Like all GReddy Supreme SP systems, the fully hand-welded 304 Stainless-Steel exhausts carry a Limited Lifetime Warranty.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eAPPLICATION\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHonda Civic SI Sedan \u003c\/strong\u003e(2017, 2018, 2019, 2020, 2021)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFully Hand-Welded 304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003eLarge 76mm (3\") Diameter Piping\u003c\/li\u003e\n\u003cli\u003eFree Flowing, Compact Dual SP Mufflers\u003c\/li\u003e\n\u003cli\u003eImproved Performance and Sound w\/o Drone\u003c\/li\u003e\n\u003cli\u003eCarefully Tuned Not To Require Additional Resonators\u003c\/li\u003e\n\u003cli\u003eFinished Off w\/ Stylish Dual, Double-Wall, Slant-Cut Tips\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eSPECIFICATIONS\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eChassis\u003c\/strong\u003e:  FC1 4door Sedan\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine\u003c\/strong\u003e:  L15  Turbo\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e:   3\" Cat-back with dual oval muffler with dual tips\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of pieces\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePiping\u003c\/strong\u003e:   76 mm (3 \")\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTips\u003c\/strong\u003e:   2x 115 mm (4.5 \")\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGasket\u003c\/strong\u003e(s):    3 \" oval (qty: 2 included) replacement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResonator\u003c\/strong\u003e:   Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e:  TBA lbs   (Stock weight  TBA lbs)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSound Comparison (SAE J1169) Test:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e TBA dB(a)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHP\u003c\/strong\u003e:  +TBA  hp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTRQ\u003c\/strong\u003e:  +TBA  ft-lbs\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GReddy","offers":[{"title":"Default Title","offer_id":14532970872876,"sku":"gre10158217","price":1122.57,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0025\/9709\/3420\/products\/4_cdd8268c-de6a-47b4-b08a-0a848784c110.jpg?v=1681303788","url":"https:\/\/www.kamispeed.com\/en-ca\/products\/greddy-2017-honda-civic-si-sedan-supreme-sp-exhaust","provider":"KamiSpeed.com","version":"1.0","type":"link"}
