CTS Turbo 3.5-inch high-flow catted downpipe for the BMW N55 with pneumatic wastegate. Replaces the highly restrictive stock downpipe.
CAD-designed for a perfect OEM fit, it is constructed from T304 stainless steel with hand-TIG welding and back-purging. It provides a sporty sound under acceleration, remains discreet at cruising speeds, and features no drone with the stock exhaust.
Compatible with BMW 335i F30 and M135i F20/F21, including xDrive models, produced between 2012 and July 2013 (N55 with pneumatic wastegate). If your car was manufactured after July 2013, you need the 4-inch version for electric wastegate. A Stage 2 tune is required to avoid a check engine light; CTS recommends Bootmod3. The warranty does not cover catalytic converters damaged by crackle tunes.
Before installing any exhaust parts on a registered vehicle, please check current local regulations.
Delivery time: 2 to 30 days. This part may not be in stock in Spain and is ordered from the manufacturer based on availability. If you need it by a specific date, please contact us before purchasing so we can confirm the timeframe.
