Overview

The Dinan DNN Axle-Back Exhaust System is a performance upgrade designed for the E90 BMW M3, specifically for the 2008-2011 model years. Constructed from 20-gauge 304 stainless steel, this system aims to improve exhaust flow while maintaining a civilized cabin sound at light throttle, and delivering a sportier note during acceleration. It features black ceramic-coated tips for a distinct aesthetic. This axle-back system weighs 10 lbs less than the stock unit.
