{"product_id":"greddy-supreme-sp-exhaust-11-14-subaru-impreza-wrx-sti-sedan-gvb","title":"GReddy Supreme SP Exhaust - 11-14 Subaru Impreza WRX STI Sedan GVB","description":"The Supreme SP for the Subaru STI Sedan features much larger diameter piping, resonators and mufflers, but also smoothes the layout for maximum performance with good sound suppression. This cat-back exhaust starts out with a full 3” mid-pipe with a large straight-through resonator to tune out drone. The next section smoothly transitions into dual 2.5” diameter piping. Improved dual GReddy straight-through mufflers with dual, double wall tips on each muffler finish off the exhaust. GReddy designers carefully position the dual mufflers and staged tips to flow with the GV-chassis’ body-lines.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eApplications\u003c\/b\u003e:\u003cbr\u003e\n\u003cul\u003e\n\t\u003cli\u003eSubaru Impreza WRX STI [GV] (2011, 2012, 2013, 2014)\u003c\/li\u003e\n\u003cli\u003eSubaru Impreza WRX [GV] (2011, 2012, 2013, 2014)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cp\u003eLarge diameter piping, resonators, and mufflers \u003cbr\u003eSmooth layout for maximum performance with good sound suppression\u003cbr\u003eFull 3” mid-pipe with a large straight-through resonator to tune out drone\u003cbr\u003eDual 2.5” diameter piping and mufflers \u003cbr\u003eDouble wall tips on each muffler \u003cbr\u003eStaged tips to flow with the GV-chassis’ body-lines\u003cbr\u003eHand-welded 304 Stainless-Steel\u003cbr\u003eLimited Lifetime Warranty\u003c\/p\u003e\n\u003ch3\u003eExtended Information\u003c\/h3\u003e\n\u003cp\u003eChassis:  GV8\u003cbr\u003eEngine:  EJ257\u003cbr\u003eType:  cat-back, dual muffler system\u003cbr\u003eNumber of pieces:  4\u003cbr\u003ePiping:   76 mm (3\") - 2x 63.5mm (2.5\")\u003cbr\u003eTip(s):  4x 89 mm (3.5\")\u003cbr\u003eGasket(s):  2x 2.5\" \u0026amp; 1x 3\" oval (qty: 3 included) replacement(s)\u003cbr\u003eResonator:   Yes\u003cbr\u003eWeight: TBA  lbs  \u003cbr\u003eSound level:  L89 \u0026amp; R91 dB(a) @4000\u003cbr\u003eNotes: reuse factory doughnut-gasket and hardward for mid-pipe\u003cbr\u003ePower: +14 whp \/ +22 ft-lbs\u003c\/p\u003e","brand":"GReddy","offers":[{"title":"Default Title","offer_id":13835932991532,"sku":"gre10168201","price":1630.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0025\/9709\/3420\/products\/greddy-supreme-sp-exhaust-11-14-subaru-impreza-wrx-sti-sedan-gvb-gre10168201-5349163171884.jpg?v=1681304652","url":"https:\/\/www.kamispeed.com\/en-ca\/products\/greddy-supreme-sp-exhaust-11-14-subaru-impreza-wrx-sti-sedan-gvb","provider":"KamiSpeed.com","version":"1.0","type":"link"}
