Description
Experience the ultimate performance upgrade for your BMW F-Chassis N55 engine with the Active Autowerke BMW N55 Catted Downpipe. Designed to unleash the true power potential of your vehicle, this high-quality downpipe enhances turbocharger performance by optimizing exhaust gas flow.
The OEM downpipe in the N55 engine is known to be restrictive, hampering the exhaust gas evacuation process and slowing down turbo spool. However, with the Active Autowerke F-Chassis N55 Signature downpipe, you can overcome these limitations. Crafted from 3.5" diameter stainless steel piping, this downpipe ensures increased power output, quicker spool, and exceptional durability.
The standout feature of this downpipe is the 4.5" high flow GESI catalytic converter, designed to deliver maximum performance without triggering a Check Engine Light (CEL). GESi G-Sport Ultra High Output Catalytic Converter features advanced construction with full 304 stainless steel, including the substrate. This EPA registered and compliant converter significantly reduces emissions, surpassing stock converters in performance and reliability.
With a flow capacity suitable for engines generating 500 to 850 horsepower, the GESi UHO-Series Catalytic Converters maintain optimal back-pressure, allowing you to maximize your engine's potential without compromising emissions standards. Bid farewell to Check Engine Lights and failed emissions tests!
Please note that these catalytic converters are not legal for use on vehicles registered in California, as they do not meet the requirements of California Vehicle Code Section 27156 and 38391.

Please note that federal law prohibits the tampering of emissions control devices. However, according to Mobile Source Enforcement Memorandum 1A, aftermarket parts can be used to repair or replace emissions control systems as long as emissions are not adversely affected. The GESI catalytic converter produces emissions that meet EPA standards but not CARB requirements.
