Looking to elevate the external acoustics of your G8x but want to upgrade in stages and/or not break the bank? The Dinan Middle Exhaust for the G80 M3 is and G82/G83 M4 introduces a more aggressive tone and an increase in volume over the stock system while retaining the factory muffler at a budget friendly price point. Should the desire for more arise however, it can easily be paired with the matching Dinan axle back exhaust for further aural enhancement and a more aggressive growl. It is a union that boasts a bold, yet sophisticated, exhaust note that neither can fully achieve on their own. This middle exhaust itself removes the hydro-formed factory center section from the secondary catalysts back to the axle back, including both resonators, and replaces it with larger 3-inch T304 stainless steel tubing for freer flowing capabilities. In place of the forward factory resonator, Dinan incorporates a beautifully crafted X-pipe made from mandrel-bent tubing for minimum restriction, unlike stamped X-pipes which are commonplace in the market. This hand-made 'X' is not only the focal point of the system in terms of aesthetics but also the star when it comes to the effects on the sound. Promoting even flow to both banks of tips, the 'X' removes unwanted nuances in sound caused by uneven exhaust flow that is present in the stock system. Along with the inherent benefit of increased volume by removal of the resonators, the Dinan X-Pipe for the G8x M3/M4 produces a louder, smoother, and fuller exhaust note that will deliver smiles time and time again. Features: Smoother, louder, and sportier sound 76mm (3-inch) tubing replaces stock 70mm (2.75-inch) tubing for free flow Deletes resonators between the secondary catalysts and rear muffler for increased volume Includes X-pipe crossover made from mandrel bent tubing for minimum restriction 5-pounds lighter than the stock mid-section (Stock: 22-pounds vs. Dinan: 17-pounds) 100% 304 stainless steel construction Factory-like fitment with included mounting hardware

The Active Autowerke G80/G82 rear exhaust was carefully engineered to increase the sound level over the factory M3 and M4 exhaust, while also allowing for optimum flow and resonance by reusing the actuators from the BMW valves. Every effort was made in addressing the overly quiet sound of the stock OEM exhaust while designing an exhaust worthy for an "M" car. We believe our rear exhaust combined with our mid-pipe and catted downpipes offers the best combination of sound and performance versus any other system on the market today. Available for both models, this axle-back exhaust gives your BMW the deep, throaty, growl a car of its caliber should have had from the factory! KEY FEATURES Made in the USA 304 Stainless Steel Low, Deep Sound with stock Valve Control Each exhaust test-fit on our G80/G82 Exhaust Fixture Guaranteed to fit all G80/G82 BMW M3/M4 Includes all necessary installation hardware At Active Autowerke, it's not ONLY about making as much power as possible but to maximize the enjoyment of the drive. For over 40 years, power has been the end result of improved performance due to our relentless desire to develop a refined, quality product. This philosophy behind our performance parts is best represented by the introduction of G80/G82 BMW M3/M4 collection rear exhaust.

For the owner of a flagship G-series M-car, Active Autowerke provides a "no-compromise" performance upgrade that prioritizes both power and daily-driver refinement. These downpipes feature integrated GESI G-Sport catalytic converters, which are EPA-registered and fully OBD2 compliant. Utilizing proprietary precious metal loading, these converters reach operational efficiency within just 9 seconds of startup, drastically reducing emissions and eliminating the pungent exhaust smells common with aftermarket pipes. Designed as a direct bolt-on replacement, this system preserves your car's sophisticated electronics while providing a deep, aggressive V8-like growl that the S58 engine was always meant to have. Key Features: Refined Exhaust Note: Increases the volume and depth of the exhaust tone while maintaining a drone-free cabin. Fast Catalyst Light-Off: Proprietary loading technology ensures emissions systems satisfy factory monitors quickly. Corrosion Resistance: High-grade T304 stainless steel substrate is furnace-braised to the mantle for outstanding durability. Precision Casting: Casted upper flanges provide superior strength compared to standard cut-and-weld alternatives. Warranty Protected: Covered by a 5-year/50,000-mile structural warranty and a 2-year/25,000-mile catalyst core warranty.* Specifications: System Type: Twin Catted Downpipes Weight Reduction: Significantly lighter than the heavy ceramic factory assemblies Flow Rating: Engineered for engines producing up to 850 HP Hardware: Includes lower mounting brackets and precision V-bands Manufacturing: Hand-fabricated in the USA Vehicle Fitment: * 2021+ BMW M3 Sedan (G80) / Competition / xDrive 2021+ BMW M4 Coupe (G82) / Competition / xDrive 2023+ BMW M2 (G87) *Important Note: The catalyst warranty is void if the vehicle is equipped with an "aggressive burble" tune, as excessive backfire can physically degrade the catalyst core over time.

Active Autowerke has introduced the Valved Rear Exhaust for the BMW G80 M3 and G82 M4. While these vehicles have received widespread acclaim for their performance, their factory exhaust system produces a subdued sound, leaving drivers questioning whether they are truly experiencing the essence of a BMW M-car. To address this, Active Autowerke has developed a rear axle-back valved exhaust system for the G80/G82. For over 40 years, Active Autowerke has prioritized not only maximizing power output but also enhancing the overall driving experience. Their commitment to performance stems from a relentless pursuit of refining and producing high-quality products. This philosophy is exemplified in the development of the G80/G82 BMW M3/M4 rear exhaust system. The Active Autowerke G80/G82 rear exhaust has been meticulously engineered to enhance the sound profile of the factory M3 and M4 exhaust while optimizing airflow and resonance by integrating the original BMW valve actuators. Significant effort was invested in addressing the muted tone of the OEM system, ensuring that this exhaust delivers a sound befitting an M-car. When combined with Active Autowerke’s mid-pipe and catted downpipes, this system offers an unparalleled blend of sound and performance compared to other options on the market. This axle-back exhaust provides the deep, aggressive growl that a high-performance BMW M-car should have had from the factory.
