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 preferance. 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!

At Active Autowerke, performance is about more than peak numbers. It’s about delivering a driving experience that feels sharper, sounds better, and maintains the refinement expected from a modern BMW. With over four decades of BMW performance development behind it, the F97/F98 X3M/X4M rear exhaust was engineered to give the S58-powered platform the deeper, more assertive tone many owners feel the factory system lacks. This axle-back system increases exhaust presence while preserving proper flow and daily drivability. By retaining the factory valve actuators, the system maintains full OEM functionality — delivering an aggressive note with the valves open and a controlled, composed tone when closed. On its own, the rear section provides a noticeable but refined sound improvement. For owners looking to maximize both sound and performance, the system pairs effectively with Active Autowerke mid-pipes and catted downpipes. Construction focuses on durability and consistent fit. The exhaust is manufactured from high-quality 304 stainless steel and each unit is test-fit on Active Autowerke’s dedicated F97/F98 fixture to ensure proper alignment and installation. Important Fitment Information A version is available for vehicles retaining the factory mid-pipes. If you later upgrade to an Active Autowerke or other aftermarket mid-pipe, different connecting pipes may be required. Sound Note: The rear section alone offers a refined increase in volume. The most significant sound change occurs when paired with an upgraded mid-pipe. Product Highlights Designed and manufactured in the USA Constructed from durable 304 stainless steel Deeper, more aggressive tone while retaining factory valve control Reuses OEM BMW exhaust valve actuators Each system test-fit on F97/F98 exhaust fixture Guaranteed fitment for F97/F98 BMW X3M and X4M Includes all necessary installation 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.

Dial In B58 Sound and Performance — the Turner Way Looking for a noticeable bump in sound and flow without replacing the entire exhaust system? The Active Autowerke Gen 2 Rear Exhaust for B58-powered BMW models delivers meaningful gains in a clean, well-engineered package. This rear section focuses on improving exhaust efficiency and tone while maintaining the refinement and daily usability expected from a properly sorted BMW. At the heart of the system is a straight-through muffler design that reduces backpressure versus the restrictive factory unit. The result is improved horsepower and torque, particularly through the midrange where the B58 responds best. With the factory valve open, the exhaust produces a more aggressive sport tone. Close the valve and the sound remains controlled and comfortable for everyday driving. Construction is centered on durability and proper fit. Large mandrel-bent tubing and a brushed 304 stainless steel body provide long-term corrosion resistance and consistent flow. Double-walled signature tips — available in brushed, black, or carbon stainless — finish the rear with a clean, purposeful appearance. Installation is straightforward thanks to height-adjustable mounting brackets and the inclusion of a heavy-duty TORCA-style clamp, known for its strong sealing capability and secure fitment. Independent testing shows gains of approximately 12–15 horsepower over stock while reducing overall weight compared to the factory rear exhaust. Product Highlights Straight-through muffler design for improved exhaust flow Retains factory exhaust valve functionality Large mandrel-bent piping supports increased performance Constructed from 100% brushed 304 stainless steel Double-walled tips available in brushed, black, or carbon finishes Adjustable tips with embossed Active Autowerke branding Noticeable horsepower and torque improvements across the RPM range Approximate gains of 12–15 HP over stock TORCA-style clamp provides a secure, leak-resistant connection Height-adjustable mounting brackets ease installation Weight reduction versus factory exhaust (22.0 lbs vs. 27.0 lbs) Includes illustrated installation instructions Covered by a two-year warranty Fitment BMW F30 340i / 340i xDrive (Sedan) — 2013+ BMW F32 440i / 440i xDrive (Coupe) — 2013+ BMW F33 440i / 440i xDrive (Convertible) — 2013+ A well-balanced upgrade for enthusiasts who want stronger sound, measurable performance gains, and OEM-like fit and function without unnecessary complexity.

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)

This is a factory BMW M Performance exhaust for the F87 M2 Competition. This is a factory BMW accessory so it fits great, looks and sounds phenomenal, and is of exceptional quality. The sound is mildly more aggressive than the stock exhaust with a slightly more throaty note. This exhaust will waken up the stock M2 Comp personality with a better sound and improved flow. If you feel the stock exhaust is just TOO quiet, this is a great option without going overboard. A unique high-tech look is provided by four Carbon Fiber exhaust tips that are laser engraved with the ///M logo.
