A full 80mm (3.15-inch) mandrel-bent titanium system feeds Invidia's tuned R400 mufflers for optimized back pressure, improved throttle response, and increased horsepower and torque. Quad straight-cut titanium-colored 4-inch tips finish the system, with titanium flanges for optimum fitment and machine welds for a clean, uniform appearance. At roughly 21 pounds, it is one of the lightest cat-backs available for the VA chassis.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2015-2021 Subaru WRX + 2015-2021 Subaru WRX STI (VA chassis, sedan)\u003c\/li\u003e\n\u003cli\u003eFull G5 titanium construction — ~21 lbs, significant weight savings\u003c\/li\u003e\n\u003cli\u003e80mm (3.15\") mandrel-bent piping; tuned R400 mufflers for optimum flow and sound\u003c\/li\u003e\n\u003cli\u003eQuad straight-cut titanium-colored 4\" tips; titanium flanges, machine-welded\u003c\/li\u003e\n\u003cli\u003eHangers welded onto OEM locations; new gaskets, hardware, and silencers included\u003c\/li\u003e\n\u003cli\u003eWith a stock downpipe, an aftermarket DP-to-cat-back adapter (e.g. GrimmSpeed) may be required\u003c\/li\u003e\n\u003cli\u003ePart HS15STI5TG4ST\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JDMuscle","offers":[{"title":"Default Title","offer_id":67700859797598,"sku":"invHS15STI5TG4ST","price":1726.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0232\/4721\/files\/DSC_1114_1080x1080_93d6a43d-8f45-48fe-ad4f-60a962205e08.jpg?v=1791565971","url":"https:\/\/slrspeed.com\/products\/invidia-15-21-wrx-15-21-wrx-sti-gemini-r400-cat-back-exhaust-full-titanium","provider":"SLRspeed","version":"1.0","type":"link"}
