If you're looking for a well-built and very light exhaust system for your track/racing 135i this is a fantastic option! This E82 Borla Race Exhaust is the full system from the downpipes to the back of the car. It's a straight-pipe design, with Test Pipes to eliminate the secondary cats, and a single rear muffler. The free-flowing design is perfect on the turbo engine as the turbo impeller(s) spin with less resistance. This is 100% stainless steel with mandrel-bent tubing from the official exhaust supplier to the Turner Motorsport race team. This system is only intended for race or track-only cars as it deletes one set of cats and has only one muffler for sound dampening. The primary stock cats in the exhaust manifolds remain untouched.

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.

This Borla race exhaust fits the following BMWs:
2008-2011 E82 1 Series 135i coupe
2008-2011 E88 1 Series 135i convertible
