This stainless steel rear exhaust section replaces the heavy (and restrictive) stock rear muffler on the 135i. Shed excess weight and restriction, and get a better sound! You will love the rich, deep sound this rear muffler gives your 135i. And if you have tuned your 135i to make more boost than stock, you will greatly appreciate the added power and reduced weight.

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:
2008-2013 E82 1 Series 135i coupe
2008-2013 E88 1 Series 135i convertible
