Featuring premium 400-cell high-flow metallic catalytic converters, these downpipes provide significantly improved exhaust flow over the factory units, helping reduce backpressure, improve turbocharger efficiency, and deliver noticeable gains in horsepower, torque, and throttle response.\u003c\/p\u003e\n\u003cp\u003eThe IRL MaxFlow design promotes smooth exhaust flow to minimize turbulence and optimize performance throughout the entire RPM range. The result is quicker turbo spool, enhanced throttle response, and a deeper, more refined exhaust note without the harshness commonly associated with lower-cell-count catalytic converters.\u003c\/p\u003e\n\u003cp\u003eManufactured from premium T304 stainless steel and precision TIG welded, every set is built for exceptional durability and long-term reliability. Designed using OEM mounting locations, these downpipes provide a direct bolt-on installation and are compatible with both the factory exhaust system and most aftermarket cat-back exhausts.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eFeatures\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIRL MaxFlow high-flow design\u003c\/li\u003e\n\u003cli\u003ePremium 400-cell high-flow metallic catalytic converters\u003c\/li\u003e\n\u003cli\u003eT304 stainless steel construction\u003c\/li\u003e\n\u003cli\u003ePrecision TIG welded for maximum strength and durability\u003c\/li\u003e\n\u003cli\u003eIncreased horsepower and torque\u003c\/li\u003e\n\u003cli\u003eImproved turbo spool and throttle response\u003c\/li\u003e\n\u003cli\u003eReduced exhaust backpressure\u003c\/li\u003e\n\u003cli\u003eRefined performance exhaust tone\u003c\/li\u003e\n\u003cli\u003eDirect bolt-on installation\u003c\/li\u003e\n\u003cli\u003eOEM-style fitment\u003c\/li\u003e\n\u003cli\u003eCompatible with OEM and most aftermarket exhaust systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eVehicle Fitment\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBMW G87 M2 (S58)\u003c\/li\u003e\n\u003cli\u003eBMW G80 M3\u003c\/li\u003e\n\u003cli\u003eBMW G81 M3 Touring\u003c\/li\u003e\n\u003cli\u003eBMW G82 M4 Coupe\u003c\/li\u003e\n\u003cli\u003eBMW G83 M4 Convertible\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eImportant Information:\u003c\/b\u003e These 400-cell downpipes are not EPA certified and are intended for off-road and motorsport use only where permitted by law. While the 400-cell catalyst design significantly reduces the likelihood of a check engine light compared to lower-cell-count catalytic converters, IRL does not offer a no check engine light (CEL) guarantee with these units. A CEL may still occur depending on vehicle software, fuel quality, driving conditions, and manufacturing tolerances. ECU tuning may be recommended to optimize performance and catalyst efficiency.\u003cspan style=\"color: #ff0000;\"\u003e\u003cb\u003e\u003c\/b\u003e\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003ca href=\"https:\/\/svbimmer.com\/pages\/emissions-notice\" target=\"_blank\"\u003e\u003cstrong\u003eEMISSIONS NOTICE\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"IRL LLC","offers":[{"title":"3” MaxFlow Catted 400 Cel","offer_id":45223089176776,"sku":"IRL-G8X-400C","price":1199.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0210\/4203\/6785\/files\/IRL-G8X-MaxFlow-Race-400-CEL-Downpipes.jpg?v=1791134062","url":"https:\/\/svbimmer.com\/products\/irl-g8x-maxflow-race-400-cel-downpipes","provider":"SVBimmer","version":"1.0","type":"link"}
