From a trusted expert in Stainless steel exhaust systems, and one of our favorite manufacturers, comes this bolt-on rear exhaust section for all 2008, 2009 and newer E90 M3 Sedan. This system is light, weighing in at only 34 lbs -- 21 pounds lighter than stock! This exhaust flows much more freely with less restriction than the stock rear muffler section, and features Borla's ATAK™ (Acoustically-Tuned Applied Kinetics) technology. This exclusive technology produces the highest available dB (decibel) levels in the BORLA® street-legal lineup, and is designed for high-performance purists who prefer exhaust notes over their stereos. The focus of ATAK™ is to pump the volume while retaining clarity of sound, at the same time avoiding the drone and distortion typically found in louder exhausts. With ATAK™, the sound output is tuned like a graphic equalizer to shape and focus sound waves for optimum high-volume output. It's made of the highest grade T-304 stainless steel, and has beautifully made symmetrical 3.5 inch quad exhaust tips. Best of all, this exhaust is a direct bolt on fitment, which does not require any cutting, welding or splicing to install. Made in the USA.

This exhaust fits the following BMWs:
