Fabricated from Grade 5 titanium, the system weighs just under 37 lbs and uses 80mm (3.15-inch) mandrel-bent piping with minimal bends to reduce exhaust turbulence under full throttle, improving throttle response and increasing both horsepower and torque. The non-resonated mid pipe and tuned N1 mufflers produce Invidia's signature aggressive N1 sound, exiting through dual 101mm (4-inch) titanium tips in a burnt blue finish. The exhaust hangers are welded onto OEM-like locations for a direct-fit installation with no extra alterations needed, and new gaskets, hardware, and a pair of removable silencers are included. Note: with a stock J-pipe or downpipe, the GrimmSpeed Subaru stock-DP-to-aftermarket-cat-back adapter (p\/n 077046) is required.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFits 2015-2021 Subaru WRX (FA20DIT) and 2015-2021 Subaru WRX STI (EJ257), sedan\u003c\/li\u003e\n\u003cli\u003eFull Grade 5 titanium construction - weighs just under 37 lbs\u003c\/li\u003e\n\u003cli\u003e80mm (3.15-inch) mandrel-bent piping, non-resonated mid pipe, dual-exit N1 mufflers\u003c\/li\u003e\n\u003cli\u003eDual 101mm (4-inch) titanium tips in burnt blue finish\u003c\/li\u003e\n\u003cli\u003eAggressive N1 exhaust note; titanium flanges for optimum fitment and durability\u003c\/li\u003e\n\u003cli\u003eDirect-fit - hangers welded onto OEM-like locations; new gaskets, hardware, and a pair of removable silencers included\u003c\/li\u003e\n\u003cli\u003eNote: stock J-pipe\/downpipe requires the GrimmSpeed stock-DP-to-aftermarket-cat-back adapter (p\/n 077046)\u003c\/li\u003e\n\u003cli\u003ePart number HS15STIDTG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JDMuscle","offers":[{"title":"Default Title","offer_id":67700867432542,"sku":"invHS15STIDTG","price":1217.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0232\/4721\/files\/invidia-n1-titanium-cat-back-exhaust-subaru-wrx-sti-2015-2019-hs15stidtg-cat-back-exhaust-system-invidia-invhs15stidtg.jpg?v=1791566057","url":"https:\/\/slrspeed.com\/products\/invidia-15-21-wrx-15-21-wrx-sti-n1-titanium-cat-back-exhaust","provider":"SLRspeed","version":"1.0","type":"link"}
