Autowerk Active Sport Catalyst Downpipe for BMW S63/N63 X5M/X6M/X5/X6 Engine

Description

Active Autowerke is proud to offer its handcrafted Signature S63/N63 downpipes for the BMW X5M, X6M, 550i, 650i, X5, and X6 models with twin-turbo V8 engines. Please note that G-body vehicles equipped with the N63B engine will require a different downpipe version. If you purchase a downpipe compatible with F-body models, it will not be compatible with your vehicle. Active is constantly conducting research and development to ensure a perfectly fitting product.

The rotational speed of a turbo wheel is primarily limited by exhaust backpressure. If some or most of this backpressure could be eliminated, the turbo would spin much faster and more effortlessly, resulting in higher engine speeds and increased horsepower. Autowerke Signature Active Downpipes are designed to maximize horsepower. They are designed with the fewest restrictions possible thanks to 3-inch piping and a minimal number of bends. You'll get a faster, more responsive engine thanks to the increased rotational speed of the turbo wheel. The result: increased horsepower. Made from 304 stainless steel, this handcrafted process ensures a strong and durable exhaust, ensuring optimal performance and longevity.

This variant includes a pair of GESI Ultra High Flow 4,5" catalytic converters that will NOT produce a CEL!

The GESi G-Sport Ultra High Output Catalytic Converter is constructed entirely of 304 stainless steel, including the substrate. GESi UHO Series catalytic converters are EPA-registered and OBD2 compliant in 49 states, making them a perfect fit for 1996 and newer vehicles. GESi's proprietary precious metal loading technology ensures significantly lower emissions, eliminating most check engine lights. These high-flow catalytic converters outperform stock converters and provide a reliable solution to the most common catalytic converter problems.

GESi UHO Series catalytic converters are designed for engines from 500 to 850 horsepower, while maintaining high flow. The reduced back pressure of this high-flow catalytic converter will allow you to maximize your engine's power without harmful emissions. Say goodbye to check engine lights and failed emissions tests!
