New to our lineup of exceptional performance upgrades for your BMW, the Turner F8X M3/M4 exhaust system is here to improve your driving experience with hearty exhaust notes and a noticeable bump in performance. Our Exhaust system sports Mandrel bent dual 2.5� 304SS pipes with a nice brushed finish. Exhaust gases flow through efficient piping to High flow, valved, stainless steel mufflers. Under normal driving conditions, the vacuum controlled muffler valves stay closed, and the exhaust is quite unassuming. Nobody will really even suspect your car even has an aftermarket exhaust system, as it sounds nearly identical to the factory system. But, when you open up the throttle, the vacuum controlled valves open up, and this exhaust gives your car a menacing growl. Designed to mount using the factory exhaust hangers, this exhaust is a bolt-on replacement for the OE version. To help reduce the time you spend installing the system, Accuseal slip-fit joints are included to make fitment as easy as possible. The Turner Motorsport full exhaust system includes a High flow, valved, stainless-steel muffler, and is available as an axle-back or cat-back system! Give your M3/M4 the dual-purpose exhaust system that satisfies both your neighbors and your need for volume with the Turner Motorsport Valved Performance Exhaust System.

The Active Autowerke F8X rear exhaust was carefully engineered to eliminate the unflattering sound of the factory M3 and M4 exhaust, while also allowing for optimum flow and resonance. Every effort was made in addressing the not so appeasing sound of the stock OEM exhaust, but in designing an exhaust worthy for an "M" car. We believe our rear exhaust combined with our mid-pipe offers the deepest sound and best performance of 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!

We set out to amplify the F80/F82 with a proper exhaust system. To accomplish this goal, our engineers at Turner increased flow and delivered an exhaust system that captures the full unrestricted sound of the twin turbo inline-6 S55 engine. The increase in flow was gained from dual 2.5" stainless exhaust pipes that feed into one of the best designed mufflers on the market. Our in-house engineers specifically designed the muffler with flow in mind to ensure that even with the exhaust valves closed, our Turner muffler flows better and sounds better than the stock muffler. The best part of the catback exhaust is the capability to control just how aggressive you want to your exhaust to sound, far beyond the point that the factory exhaust is able to perform. All of this plus the direct fitment and straight forward installation leads to the Turner Stainless exhaust being the clear answer in your mission to find the best exhaust for your S55 powered F80 or F82.

Transform the whole dynamic of your M3 or M4 with added performance, increased flow and not to mention the absolutely wicked sound you get from the upgraded Turner Performance Catback!

Active Autowerke is proud to announce the release of the Signature F8X M3/M4 Exhaust System. This system is the result of countless hours of R&D to obtain the perfect combination of performance and sound. Constructed of 100% 304 TIG welded stainless steel, Active Autowerke has created a modular exhaust system that will provide enough flow to support power levels way above the stock S55. The stock S55 Midpipe is a dual-pipe system from each turbo that leads to the rear muffler. The resulting sound is far from pleasant, and without any real scavenging effect the turbo lag is fairly pronounced. By converting to a single 3.5" pipe directly after the downpipes, AA's system promotes exhaust scavenging along with higher exhaust velocity to produce a quicker spool, more power, and a much smoother exhaust note.
