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.

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.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preference. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. 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! This product modifies (but does not remove or defeat) emissions equipment. For this reason this product may not be CARB compliant, and therefore not emissions legal in some states. Consult local laws and regulations in your area. For more information on this product, feel free to contact our sales department.
