Section: complete exhaust from the downpipe-back, non resonator, Borla performance muffler
Installation: clamp-on
Tip Style: round 88mm Borla angle cut


This stainless steel rear exhaust section replaces the heavy (and restrictive) stock exhaust system on the F30 335i F32 435i. Shed excess weight and restriction, and get a better sound! The ATAK system -- Acoustically Tuned Applied Kinetics -- allows a very high volume without drone and distortion. This is beyond 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. And if you have tuned your 335i to make more boost than stock, you will greatly appreciate the Borla design without the restrictive resonator and 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.

This Borla Exhaust fits the following BMWs:
2012+ F30 BMW 335i - Sedan
2013+ F32 BMW 435i - Coupe
2013+ F33 BMW 435i Convertible
