Optimal power, performance and sound are the core values of our Active Autowerke BMW 328i exhaust system, designed to fit BMW 325i, 328i, and 330i E9X N52 models. A free-flow design and beefy 80mm dual exhaust tips allow 35% to 40% more exhaust flow than the stock BMW 328i exhaust system. The increased flow minimizes back pressure, resulting in substantial HP and torque gains. The system’s Brushed stainless steel construction also makes a bold visual statement, while also increasing durability. Factory-fit specifications are followed closely, yet AA's system allows 14lbs in weight savings as opposed to the factory BMW exhaust. This exhaust features the Active Autowerke Muffler and Noise Cancellation Chamber to assist in reducing/eliminating drone. Manufactured from 100% brushed 304 stainless steel, this clamp-on system is suited for the N52 owner looking to bring their BMW's performance to new heights. NOTE: This exhaust may not easily fit some of the XI (4WD) and Station Wagon Models - welding may be required for proper fitment of the exhaust to stock pipe. Exhaust system requires cutting of the factory pipe for installation. Dimensions and cutting points are highlighted in the instructions. Some models have a round tubular pipe that makes the installation seamless. Other models have an oblong shape and will require welding instead of clamping.

This is the most aggressive muffler section that Borla produces for the E90/E92 M3. Their ATAK system - A costically T uned A pplied K inetics - allows a very high volume without drone and distortion. This is beyond your the usual 'muscle car' sound - this is full blown automotive thunder! Borla manages the sound waves inside the exhaust to produce an exhaust note that maintains its tone as revs rise. With ATAK, the sound output is tuned like a graphic equalizer to shape and focus sound waves for optimum high-volume output. 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. For an exhaust that really emphasizes the M3's motorsport background this is THE exhaust system.
Every Borla is made with 304 stainless steel for the internals and muffler body. Unlike other systems that can use coated aluminum, mild steel, or 409 stainless, the Borla uses true 304 stainless on the inside as well as the outside. This prevents the muffler from rusting and deteriorating from the inside out. Borla guarantees every muffler with a 1,000,000 mile warranty. Turner Motorsport has been the leading Borla dealer for BMW exhausts since we sold our first system in 1996, including using Borla Exhausts on every Turner BMW racecar.
This Borla Exhaust fits the following BMW models: 2008-2012 E92 BMW M3 coupe 2008-2012 E93 BMW M3 cabrio Show More Show Less
