Engine Power and Performance

The Active Autowerke Signature downpipes are engineered to eliminate exhaust back pressure, allowing the turbo to spool faster and more efficiently. This results in quicker engine revs and increased horsepower, providing a noticeable boost in performance. Constructed from 304 stainless steel, these downpipes are built to last, ensuring trouble-free performance and longevity. The inclusion of a pair of 4.5" ultra high-flow GESI catalytic converters guarantees a smooth flow without the risk of a Check Engine Light (CEL), enhancing both performance and reliability.

High-Flow Catalytic Converters and Durability

Each downpipe set comes with GESi G-Sport Ultra High Output Catalytic Converters, featuring full 304 stainless steel construction, including the substrate. These converters are EPA registered and compliant for 49 states and fully OBD2 compliant, making them perfect for use on 1996 and newer vehicles. The proprietary precious metal loading technology ensures greatly reduced emissions, eliminating most CELs. The high-flow design allows for maximum power output without compromising emissions, making these downpipes an ideal choice for engines producing 500 to 850 horsepower. Withstanding up to 1500°F, these downpipes are designed for durability and efficiency, reaching operational efficiency within 9 seconds of startup. Their easy bolt-on design requires no cutting or welding, ensuring a hassle-free installation.
