Let’s be honest—what’s the point of owning a B48-powered BMW if you can’t hear it? The factory G2X 330i/430i rear muffler assembly is oversized, heavy, and overly restrictive, muting the deep, aggressive tone that your engine was designed to produce. Our Muffler Delete System is the perfect solution for enthusiasts looking to unleash that signature turbocharged soundtrack without the cost of a full cat-back system.

Engineered and manufactured in-house, this system replaces the factory rear muffler with a free-flowing, TIG-welded 304 stainless steel setup designed to enhance tone, reduce weight, and maintain OE-level fitment and quality. At the front, 3" primary tubing mates seamlessly to your factory midpipe using a durable stainless steel sleeve clamp. At the rear axle, the primary tubing transitions to dual 3" adjustable tailpipe sections for a clean, yet aggressive look. These tailpipe sections offer compatibility with our suite of 4" exhaust tips, allowing you to tailor the system's appearance to your liking. Accuseal-style, slip-fit joints allow for easy adjustment, ensuring perfect tip placement inside the factory rear diffuser. The result? A more engaging exhaust note and a clean, motorsport-inspired appearance that transforms your BMW’s personality both visually and acoustically.

Active Autowerke’s G8X Valved Rear Exhaust section is the result of over 40 years of BMW-specific R&D. While the primary goal is a superior sound signature, the engineering team focused heavily on optimum exhaust flow and weight reduction. By replacing the dense factory muffler assembly with a streamlined stainless steel unit, this exhaust reduces weight hanging off the rear of the car while maximizing exhaust gas scavenging. The internal geometry is designed to provide a smooth transition of gases, which is critical for maintaining turbocharger efficiency on high-horsepower builds. Key Features: OEM+ Integration: Reuses the stock BMW valve actuators, meaning no extra wiring, controllers, or dash errors. Resonance Control: Internal muffler chambers are tuned to eliminate cabin drone while allowing the S58 character to shine under load. Industrial Durability: Full 304 Stainless Steel construction ensures maximum resistance to heat cycles and corrosion. Fitment Guaranteed: Every exhaust is test-fitted on an in-house G8X fixture as part of a rigorous quality control measure. Specifications & Tip Options: Configuration: Valved Axle-back (Connects to factory or aftermarket mid-pipes) Installation: Bolt-on design; includes all necessary heavy-duty clamps and hardware Available Tip Styles: Brushed Stainless Steel Matte Black Coated Genuine Carbon Fiber Vehicle Fitment: * 2021+ BMW M3 Sedan (G80) 2021+ BMW M4 Coupe (G82) 2021+ BMW M4 Convertible (G83)

Recognized for producing performance saloons, BMW's reputation soared with the establishment of its renowned M Division in the 1970s. A pivotal moment came with the introduction of the E30 M3 in 1986, a model that garnered numerous championship victories in touring car racing. Among the first exhaust systems Scorpion developed was a performance exhaust tailored for the E30 M3. Concurrently, Scorpion introduced the iconic DTM tailpipe to the UK market. Since then, Scorpion has remained a trailblazer in crafting performance exhausts for BMW's M cars and various other models. Available for this application is a T304 stainless steel 70mm high-flow GPF-back exhaust half system equipped with a valve plate for OE valves. The system boasts a high-flow profile and incorporates an acoustic rear silencer to mitigate drone. Once integrated into the BMW, the newly installed free-flowing GPF-back half system enhances the vehicle's power and refines throttle response while reducing overall weight. A notable feature of the system is its deep, throaty soundtrack, complete with crackles and pops when in sport mode. Moreover, it maintains a deep and sporty sound in normal mode without being overly intrusive for daily driving. The system, lighter than the OE counterpart, offers a choice between 114mm polished Daytona or premium quality Carbon Ascari tailpipes. For those seeking further tuning options, a 70mm/2.75” resonated or non-resonated GPF Delete option has been introduced. Crafted from T304 stainless steel using CNC Mandrel bending, this option is tailored for drivers aiming to elevate performance to the next level. The de-restrictive design facilitates increased exhaust gas flow, resulting not only in enhanced performance but also in a deeper, sportier exhaust note.
