Crafted from high-strength 6031 billet aluminum and finished in a sleek black anodized coating, it delivers both durability and corrosion resistance. With this collar in place, your exhaust stays exactly where it should—no rattles, no surprises.

Made from precision machined 6061 aluminum Black anodized finish Stainless steel M5 X 0.8mm hardware Installation & Support:

When deciding on the right exhaust the hardest part is feeling confident in the best sound mixed with increased performance, this really leaves you to guess based on reputation. Fortunately, Supersprint has the reputation covered when it comes to BMW exhausts. For over 60 years their goal has always been designing and building the highest quality exhaust available. This has been achieved through extensive testing using real race teams to get the best feedback there is to offer, from the ones who demand the best every day. Extensive dyno testing, high-quality materials, and race team feedback are what allow Supersprint to extract the power from your engine, not just the noise. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

Awaken the B58: Active Autowerke G20 M340i / G22 M440i Valved Axle-Back Exhaust From the factory, the G-series M340i and M440i are notoriously quiet, leaving the sonorous B58 inline-six feeling a bit muffled. Active Autowerke’s valved rear exhaust is the solution for enthusiasts who want to bridge the gap between "daily driver" and "motorsport-inspired." This axle-back system was engineered to replace the lackluster stock muffler with a high-flow, 304 stainless steel unit that captures a deep, hearty growl worthy of the BMW 'M' badge. By reusing the factory valve actuator, this system keeps your driving modes functional—providing a refined tone for the commute and a rowdy, unrestricted bark when you’re in the mood to let it rip. It’s the perfect "OEM+" upgrade that delivers the aggressive sound your BMW should have arrived with. Engineering & Tone Active Autowerke spent months fine-tuning the resonance of this system to ensure it provides a low-frequency rumble without the high-pitched rasp found in cheaper alternatives. Valved Versatility: Retains full integration with your factory BMW drive modes (Eco, Comfort, Sport). High-Flow Design: Maximizes exhaust gas scavenging for improved throttle response and midrange punch. Aggressive Styling: Available with quad tips to fill out the rear diffuser and provide a menacing track-ready look. Key Features: Hand-Built Quality: Fabricated in the USA from premium T304 Stainless Steel. Precision Fitment: Every unit is test-fitted on a dedicated G-series fixture to guarantee a perfect bolt-on install. Motorsport-Inspired Sound: Replaces the whisper-quiet factory muffler with a deep, throaty signature note. All-Inclusive Kit: Includes all necessary clamps and hardware for a straightforward installation. Specifications: Material: Mandrel-bent 304 Stainless Steel Type: Valved Axle-Back (Requires cutting of factory mid-pipe for installation) Valve Operation: Compatible with OEM BMW actuator Vehicle Fitment: * 2019+ BMW M340i / M340i xDrive (G20) 2021+ BMW M440i / M440i xDrive (G22/G23/G26)

Awaken the B58: Active Autowerke G20 M340i / G22 M440i Valved Axle-Back Exhaust From the factory, the G-series M340i and M440i are notoriously quiet, leaving the sonorous B58 inline-six feeling a bit muffled. Active Autowerke’s valved rear exhaust is the solution for enthusiasts who want to bridge the gap between "daily driver" and "motorsport-inspired." This axle-back system was engineered to replace the lackluster stock muffler with a high-flow, 304 stainless steel unit that captures a deep, hearty growl worthy of the BMW 'M' badge. By reusing the factory valve actuator, this system keeps your driving modes functional—providing a refined tone for the commute and a rowdy, unrestricted bark when you’re in the mood to let it rip. It’s the perfect "OEM+" upgrade that delivers the aggressive sound your BMW should have arrived with. Engineering & Tone Active Autowerke spent months fine-tuning the resonance of this system to ensure it provides a low-frequency rumble without the high-pitched rasp found in cheaper alternatives. Valved Versatility: Retains full integration with your factory BMW drive modes (Eco, Comfort, Sport). High-Flow Design: Maximizes exhaust gas scavenging for improved throttle response and midrange punch. Aggressive Styling: Available with quad tips to fill out the rear diffuser and provide a menacing track-ready look. Key Features: Hand-Built Quality: Fabricated in the USA from premium T304 Stainless Steel. Precision Fitment: Every unit is test-fitted on a dedicated G-series fixture to guarantee a perfect bolt-on install. Motorsport-Inspired Sound: Replaces the whisper-quiet factory muffler with a deep, throaty signature note. All-Inclusive Kit: Includes all necessary clamps and hardware for a straightforward installation. Specifications: Material: Mandrel-bent 304 Stainless Steel Type: Valved Axle-Back (Requires cutting of factory mid-pipe for installation) Valve Operation: Compatible with OEM BMW actuator Vehicle Fitment: * 2019+ BMW M340i / M340i xDrive (G20) 2021+ BMW M440i / M440i xDrive (G22/G23/G26)

For those that wish to have options to limit the soundtrack for late night or early morning arrivals/departures, factory valve control is retained. No matter the situation the Dinan valved axle back exhaust system is the answer for the discerning enthusiast looking for performance without sacrifice. The Dinan G20 330i / G22 430i exhaust grants the B46/B48 4-cylinder improved exhaust flow by reducing back pressure, and also creates a deeper and fuller note, without any added drone or other negative side effects.. The goal of OEM+ and then some. This Dinan exhaust system is a straightforward install with fitment like you would expect from the manufacturer using factory cut points and mounting mechanics. Going from the plebeian stock dual slash cut 90mm (3.5") tips to the massive Dinan straight cut 102mm (4") ones leaves no doubt that something above and beyond is present. This is solidified by the Dinan logo laser engraved on the tips and the deep growl of the exhaust that is indisputably different than anything one would expect to hear from a base 4-cylinder turbo platform. Features: Maximum gains of +4 HP and +3 ft-lb of torque Enjoyably louder, sportier sound Drone abatement technologies used to reduce cabin resonance Dual 4" (102mm) double-walled, polished clamp-on tips with laser engraved Dinan logo Larger diameter piping for increased flow (85mm to dual 60mm vs. 85mm to dual 83mm) 100% 304 Stainless Steel construction Retains factory valve control Factory-like fitment with included mounting hardware
