Description
Transform the sound, flow, and overall character of your BMW M3 or M4 with this REMUS Axle-Back Exhaust with Carbon Tips + Active Autowerke Midpipe Combo. This performance exhaust package combines a REMUS axle-back exhaust system with Carbon 102mm angled tips featuring titanium internals and an Active Autowerke single midpipe, creating a comprehensive exhaust upgrade designed for improved flow, increased performance, and a deeper, more aggressive exhaust note.
The Active Autowerke Midpipe was engineered to address the restrictive design of the factory BMW F8X midpipe. Its freer-flowing single-pipe configuration reduces exhaust back pressure and improves exhaust flow through the system. Active Autowerke developed the single midpipe after researching the characteristic high-pitched "weed-eater" sound associated with the factory F8X exhaust. By changing the exhaust configuration and using a single midpipe, the system is designed to produce a deeper and throatier exhaust tone.
The Active Autowerke midpipe uses a large 3.5-inch exhaust path while maintaining appropriate ground clearance through its oval pipe design. It is engineered for an exact fit on the BMW F80 M3 and F82 M4 platforms.
Completing the system is the REMUS axle-back exhaust, paired with REMUS Carbon 102mm angled titanium-internal quad tips. The combination provides a premium appearance while complementing the increased exhaust flow and more aggressive sound produced by the Active Autowerke midpipe.
Together, the REMUS axle-back and Active Autowerke midpipe create a performance-focused exhaust combination for BMW enthusiasts looking for improved exhaust flow, enhanced turbo response, increased power potential, and a deeper, more aggressive exhaust note.
