With similar features as our coupe version, the longer sedan version features high-flow with refined exhaust note. Under wide-open-throttle, spirited driving, the system offers the classic GReddy deep exhaust growl. To enhance the performance of the turbocharged 1.5L engine, this 3piece,  cat-back exhaust connects to the factory piping (our system bolts to the factory exhaust system at the flange behind the engine\/transmission) and expands to large 3” (76mm) forward-midpipe and mid-pipe that split to two polished, straight-through SP oval mufflers and dual center-exit dual-wall GReddy tips. The sedan version has a slight more aggressive tip angle and muffler combination is a better compliment to the Si sedan’s sporty, but wide rear bumper tip opening.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eChassis\u003c\/strong\u003e:  FC1 4door Sedan\u003cbr\u003e\u003cstrong\u003eEngine\u003c\/strong\u003e:  L15  Turbo\u003cbr\u003e\u003cstrong\u003eType\u003c\/strong\u003e:   3\" Cat-back with dual oval muffler with dual tips\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNumber of pieces\u003c\/strong\u003e: 3\u003cbr\u003e\u003cstrong\u003ePiping\u003c\/strong\u003e:   76 mm (3 \")\u003cbr\u003e\u003cstrong\u003eTips\u003c\/strong\u003e:   2x 115 mm (4.5 \")\u003cbr\u003e\u003cstrong\u003eGasket\u003c\/strong\u003e(s):    3 \" oval (qty: 2 included) replacement\u003cbr\u003e\u003cstrong\u003eResonator\u003c\/strong\u003e:   Yes\u003c\/p\u003e","brand":"Greddy","offers":[{"title":"Default Title","offer_id":50612401832226,"sku":"10158217","price":900.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0912\/5052\/4450\/files\/10158217gr.webp?v=1763685429","url":"https:\/\/rlperformanceracing.com\/products\/greddy-supreme-sp-exhaust-honda-civic-si-sedan-17-21","provider":"Redline Performance Racing","version":"1.0","type":"link"}
