Dinan Free Flow Axle-Back Exhaust System with Black Tips for BMW M3 Sedan (
E90) 2008-2011
Special Note: This fits the M3 Sedan only.
Dinan, the top research company in the BMW aftermarket, has a proven legacy of performance, having powered back-to-back Rolex Series Daytona Prototype racing championships from 2010 to 2012 and winning the prestigious 24 Hours of Daytona in 2013 with Chip Ganassi Racing. This excellence is the foundation of Dinan’s Free Flow Axle-Back Exhaust systems, where cutting-edge technology is brought directly to BMW owners who value both performance and refinement.
Dinan’s Free Flow Axle-Back Exhaust is designed to optimize flow and sound without compromising on either. The Helmholtz chamber, a key feature, reduces the drone that commonly affects aftermarket exhausts at low throttle, making for a quieter, more refined driving experience. The exhaust also features a straight-through single pipe design that further reduces noise during light throttle while delivering a sportier and more aggressive exhaust note at wide-open throttle.
In addition to improving performance, Dinan's exhaust is built for durability and weight savings. Constructed from 100% 20-gauge 304 stainless steel, this system is lighter than stock by 10 pounds, which contributes to better overall vehicle dynamics. The system features quad 3" black ceramic-coated tips that are laser-engraved for a sleek look, perfectly complementing the BMW’s aesthetic. Dinan’s approach to performance without sacrificing everyday drivability is a testament to its focus on maintaining BMW’s hallmark refinement.
