Designed with the latest CAD technology to fit perfectly in place of the restrictive factory catalytic converters, they are manufactured from cast T304 stainless steel, hand TIG welded and back-purged for years of reliable service. Beyond unleashing the 4.4 twin-turbo S63, they deliver a louder, deeper growl with pronounced crackle on downshift and a confident punch through all 8 gears — even louder with an aftermarket exhaust.\u003c\/p\u003e\u003ch3\u003eDetails\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e80mm or 3.15\" diameter piping\u003c\/li\u003e\n\u003cli\u003eDesigned and tested on a real car in the real world\u003c\/li\u003e\n\u003cli\u003eCast T304 stainless steel, TIG welded and back-purged\u003c\/li\u003e\n\u003cli\u003eReplaces the restrictive factory catalytic converter\u003c\/li\u003e\n\u003cli\u003eIncredible sporty sound, subtle when cruising\u003c\/li\u003e\n\u003cli\u003eNo drone with factory exhaust\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment (M cars with S63 engine only)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e2018-2024 F90 BMW M5 (including Competition models)\u003c\/li\u003e\n\u003cli\u003e2019-2024 G15\/G16 M8 Coupe, Convertible and Gran Coupe (including Competition models)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eStage 2 tuning software must be used to remove the CEL that will occur.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eEmissions disclaimer:\u003c\/strong\u003e This product is not legal for sale or use on pollution-controlled vehicles operated on public roads and is intended for off-road, race, or closed-course competition use only.
