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. 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

On a turbocharged vehicle, any restriction in the exhaust system reduces peak horsepower. By removing the factory catalytic converter, most of this restriction is removed gaining advantages in more than just peak horsepower. The factory downpipe, while excellent for maintaining strict emission regulations, does nothing to unlock the performance of a turbocharged engine. Due to an internal honeycomb structure that the exhaust gasses must pass through, flow is massively reduced. Additionally, this honeycomb causes turbulence after the converter which slows exhaust flow even further and causes more restriction. If you've ever tried to blow through a coffee straw, you know how your car feels. This not only limits how fast the turbo can spool or come up to speed but also how much air it can move in general. When the internal honeycomb structure is removed in favor of a straight and hollow piece, these issues are alleviated. Not only can the turbocharger come up to max rpm faster, is does this more efficiently and with less work since there is no back-pressure against the turbine wheel. Turbo lag becomes a thing of the past and because of this, the powerband shifts and massive top-end gains can be felt. Constructed out of 100% 304-grade stainless steel and fully mandrel bent, you can be sure that as much time has been put into construction as development. They are 100% TIG welded by in-house fabricators and built in the USA. The factory turbocharger turbine housing utilizes a V-Band flange which Evolution have duplicated and CNC machined cut out of billet 304 stainless steel. Stainless Steel CNC machined O2 sensor and laser cut brackets are TIG welded using stainless steel rods and the O2 sensor is positioned at the factory location.
