BMW Catted Downpipes - Active Autowerke 11-041
Active Autowerke is proud to bring you our hand made Signature S63 N63 Downpipes for the twin-turbo V8 BMW X5M, X6M, 550i, 650i, X5, X6 models.
A turbo impeller wheel speed is mostly limited by the exhaust back pressure within the system. If one could eliminate some or most of this exhaust back pressure, the turbo will spool that much faster and effortlessly resulting in quicker engine revs and increased HP. The Active Autowerke Signature down pipes are designed with the intent to maximize power. These down pipes are created with the least amount of restrictions possible by utilizing a full 3" piping throughout with the least amount of bends possible. What you will experience is a faster, more responsive engine because the turbo impeller now has the ability to spool that much faster. The end result is more power. Made from 304 stainless steel the handmade construction process ensures a robust and durable exhaust that will provide trouble free performance with the longevity to match.
This variant includes a 4.5" high flow GESI catalytic converter that will NOT produce a CEL!
The GESi® G-Sport Ultra High Output Catalytic Converter features full 304 stainless steel construction, including the substrate. GESi® UHO-Series Catalytic Converters are EPA certified in 49 states and fully OBD2 compliant, perfect for use on 1996 and newer vehicles. GESi® proprietary precious metal loading technology ensures greatly reduced 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.
The GESi® UHO-Series Catalytic Converters are rated for engines putting out between 500 and 850 horsepower while maintaining a high flow capacity. The reduced back-pressure from this high flow catalytic converter will allow you to maximize your engines horsepower without the harmful emissions. Say goodbye to Check Engine Lights and failed emissions tests!
Please Note: These catalytic converters are not legal for use on vehicles registered in the state of California as a result of California Vehicle Code Section 27156 and 38391.
NOTE: Federal law prohibits the tampering of an emissions control device. Mobile Source Enforcement Memorandum 1A, allows for aftermarket parts to be used in the repair or replacement of emissions control systems, provided the emissions aren’t adversely affected. There is no mention or reference to cell density or converter volume dimension. The GESI catalytic converter will produce emissions that will meet the standards set by the EPA, not CARB.

Brothers Mike and Karl Hugh were bred to play with power, it seems. As young men growing up on an island, doing things correctly for oneself became their ingrained credo. Their adolescent projects – bicycles and dirt bikes – were always the best performing. And that soon set the tone for the BMW tuning hobby they graduated to. By 1981, Mike and Karl were ready to get serious about their longstanding passion for a higher standard of BMW performance. Active Autowerke was born. Their motto at the time: "Anything and Everything BMW". They probably should have included “everyone” in there, too – since the endeavor was a classic family affair – with many branches of the Hugh family tree pooling their talents. The timing was ideal, and the company quickly grew as America’s motoring public developed a healthy appetite for the Bavarian treat. Soon Active Autowerke had grown into the largest independent BMW service center in Florida – with the most sophisticated equipment arsenal in the industry, certifications from leading componentry firms such as the Robert Bosch Corporation, and repute for setting the benchmark for service, integrity and professionalism.
