Description
Enhance the power and performance of your V8 BMW X5 M, X6 M, 550i, or 650i with Active Autowerke's Signature S63/N63 Downpipes. Handcrafted with precision and designed to maximize power, these downpipes deliver unparalleled turbo performance and effortless engine revs. By reducing exhaust back pressure with their full 3" piping and minimal bends, these downpipes allow the turbo impeller to spool faster, resulting in increased horsepower and a more responsive engine.
Crafted from durable 304 stainless steel, Active Autowerke's downpipes ensure trouble-free performance and longevity. The included 4.5" ultra high flow GESI catalytic converters eliminate the need to worry about a Check Engine Light (CEL). Featuring full 304 stainless steel construction, including the substrate, these catalytic converters are EPA registered and compliant for 49 states and fully OBD2 compliant.
The GESi G-Sport Ultra High Output Catalytic Converter is engineered with proprietary precious metal loading technology, reducing emissions and preventing most "Check Engine Lights." These high flow catalytic converters outperform stock converters, providing a reliable solution to common catalytic converter problems. Rated for engines producing between 500 and 850 horsepower, these catalytic converters maintain a high flow capacity while reducing back-pressure.
Please note that these catalytic converters are not legal for use on vehicles registered in California due to state regulations. However, federal law allows for the use of aftermarket parts in emissions control systems repair or replacement, provided emissions are not adversely affected. The GESI catalytic converter meets EPA standards, ensuring compliance outside of California.
For accurate fitment, please provide your VIN number during the ordering process. Please note that these downpipes are custom made in-house, which may result in a shipping time of up to 2 weeks.
