Power Gain: +12hp

These Borla mufflers will give your M3 a bit more growl and presence. These are stainless steel, high-flow mufflers that bolt on to the stock center section (or Borla midpipe). The stock M3 muffler is very large and softens the S54's exhaust note quite a bit. The Borla mufflers are much smaller and lighter with much-improved flow that increases horsepower and performance. Borla compared their mufflers with a common aftermarket brand and found their's flowed 10% better (click here for Borla comparison). The Borla system saves over 20lbs from the stock muffler.

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.
