Overview

The CTS Turbo Race 3.5" Downpipe is a catless downpipe designed to maximize exhaust flow for increased power gains and an enhanced exhaust sound. Manufactured from T304 stainless steel with hand TIG welded and back-purged construction, this downpipe replaces the restrictive factory unit.

It is precisely designed and tested for a perfect fit and offers an incredible sporty exhaust sound that remains subtle when cruising, with no drone when paired with the factory exhaust. Stage 2 software is required to avoid a check engine light.
Show original supplier description
The CTS Turbo Race 3.5" Downpipe is engineered to maximize exhaust flow, leading to significant power gains and an aggressive, sporty exhaust note. This downpipe delivers an incredible sporty exhaust sound that is subtle during cruising and eliminates drone when used with the factory exhaust system. To prevent a check engine light (CEL), proper tuning software, such as Bootmod3, is required. This product is intended for off-road use only. Application Guide: This downpipe is designed for the F30 BMW 335i & 335xi and the F20/F21 BMW M135i & M135xi manufactured between 2012 and 07/2013. Vehicles with a production date after 07/2013 will require the 4" downpipe (CTS-DP-0024-N55PWG). It does not fit RHD vehicles. Note: Stage 2 software is required to avoid a check engine light.
