At its heart is a massive 4.5\" mandrel-bent 304 stainless steel main section, the largest-diameter exhaust available for this chassis. By keeping a true single path front to back, it eliminates the turbulence and restriction of factory and dual-pipe aftermarket systems, for faster turbo response, maximum exhaust velocity, and a raw, aggressive note that stands apart.\u003c\/p\u003e\u003cp\u003eOpen the valve and gases take the unrestricted 4.5\" path for the loudest, most aggressive tone possible. Close it and flow is redirected through a quieter route for comfortable, drone-free cruising. The system uses a single valve — the second is simply tucked and zip-tied away, with no codes or issues from running one valve. It finishes with quad RVNG signature perforated tips that blend OEM-inspired styling with motorsport performance.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFirst and only 4.5\" true single exhaust for the G80 \/ G82 platform\u003c\/li\u003e\n\u003cli\u003eFull valved system for on-demand sound control\u003c\/li\u003e\n\u003cli\u003eHorsepower and torque gains when paired with a tune\u003c\/li\u003e\n\u003cli\u003eMandrel-bent, TIG-welded 304 stainless steel\u003c\/li\u003e\n\u003cli\u003eSmooth, uninterrupted bends for maximum flow\u003c\/li\u003e\n\u003cli\u003eSignature RVNG quad perforated tips (multiple finishes available)\u003c\/li\u003e\n\u003cli\u003eWorks with OEM or aftermarket midpipes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e2021+ BMW G80 M3\u003c\/li\u003e\n\u003cli\u003e2021+ BMW G82 M4\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eBacked by the RVNG RaceWorks lifetime warranty against defects and fitment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eEmissions disclaimer:\u003c\/strong\u003e This product is intended for off-road, race, or closed-course competition use only and is not legal for use on pollution-controlled vehicles operated on public roads in most states and provinces.
