Active Autowerke N55 Signature Downpipe Benefits
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 our 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, our 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.

Constructed entirely from 304 stainless steel with 1.5MM wall thickness, we are confident that you'll be pleased with how robust and durable this down pipe is. Trouble-free installation and a long lifespan ensure that you'll enjoy many miles of performance with your N55!
