The Borla 'Aggressive' system for the E90/E92 335i is a cat-back system comprised of no resonators, x-pipe section, and dual rear mufflers. This system was Borla's response to a demand for greater volume for the 335's twin-turbo N54 motor. The turbos make the car quieter so having a performance exhaust will allow you to finally hear the engine. Borla has tuned this exhaust to give more of a throaty burble, especially at low RPM while maintaining acceptable sound levels for daily street use. This Borla system is perfect if you want to hear the exhaust but not annoy the people in the car next to you. And this is a true cat-back system so no catalytic converters or emissions equipment is affecting by installing this. And with a free-flowing design this will allow a modest bump in power output. The Borla system is also a lot lighter than the factory system; less weight = more performance!

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.
