Borla's latest engineering advancement is the ATAK system - A costically T uned A pplied K inetics technology which allows a very high volume without drone and distortion. Borla engineers manage 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. The sound is aggressive and minus a lot of the tinny rasp sound of other exhausts. For an exhaust that really emphasizes the M3's motorsport background this is THE exhaust system.

This system replaces the E46 M3's Section 2 and rear muffler. It bolts to the stock Section 1 (or aftermarket equivalent) and uses all of the original hangers and gaskets. 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 all of every Turner BMW racecar.

This item fits the following BMWs:
2001-2006 E46 BMW M3
