The Active Autowerke N55 Downpipe Exhaust Upgrade (Part 11-028) is engineered specifically for BMW F-Chassis N55 models€”M235i, 335i, 435i, and M2€”equipped with the direct-injection, single-turbo engine from 2012 onwards. This downpipe addresses the restrictive nature of the OEM component to optimize exhaust flow and turbocharger performance.

• 3.5" diameter 304 stainless steel piping for durability and maximum exhaust flow
• Designed to minimize exhaust back pressure and maximize turbo spool speed
• Direct bolt-on fitment with no cutting or welding required
• Modular construction to support future upgrades
• Precision engineered for exact fitment on all F-Chassis N55 models from 09/2013 and later

By reducing exhaust restrictions, this downpipe aids in quicker turbo spool and improved power delivery. Constructed with 1.5mm wall thickness stainless steel, it balances performance enhancement with long-term durability. Installation is straightforward, retaining OEM mounting points for a secure fit.

Important Note: This downpipe modifies the factory emissions system and is intended for off-road or racing use only. Installation will trigger a Check Engine Light (CEL) unless paired with an appropriate Active Autowerke software upgrade. Ensure compatibility with your vehicle's specifications before purchase.
