The speed of a turbo’s impeller wheel is limited by exhaust back pressure. A larger down pipe relieves some of this pressure, resulting in quicker and more efficient spool. With Active Autowerke’s Signature downpipe, your N55 can rev quicker, and deliver more horsepower and torque.

Minimizing back pressure while remaining daily drive-ability was the goal of this N55 downpipe. Owners can now upgrade to a product that is affordable, reliable, and easy to install. Note: Because this down pipe modifies the factory emissions system it is designed for off-road or racing use only.

After months of research and development, Active Autowerke engineers settled on a 3.5” diameter pipe which utilizes the least number of bends possible. However, the Signature N55 down pipe still fits easily into the OEM location, with a painless installation process.

NOTE:

• FITS ALL F-CHASSIS N55 CARS FROM 09/2013 UP ONLY
• THIS DOWNPIPE SYSTEM IS DESIGNED FOR OFF ROAD AND RACING APPLICATIONS ONLY.
• BMW N55 WITH THIS DOWNPIPE WILL THROW A CEL WITHOUT AN ACTIVE AUTOWERKE SOFTWARE UPGRADE FOR OFF-ROAD USE ONLY.
