Active Autowerke BMW Downpipes

When BMW began to offer more and more forced induction vehicles, some enthusiasts were upset and others were excited about the big power potential. While we love older, naturally aspirated BMWs, we LOVE forced induction BMWs. Upgrading your downpipe (or downpipes) is one of the easiest ways to reduce restriction and add more power to your BMW. We offer several brands, including our own designs, of downpipes for your BMW!

BMW introduced a new valvetronic, single turbo version of its direct-injection engine for the F-Chassis models beginning in 2012. The Active Autowerke N55 downpipe for the M235i, 335i, 435i and M2 helps unleash some of the potential that is restricted by the OEM downpipe. Turbochargers are powered by spent exhaust gases created during the combustion process. The quicker these gases are evacuated, the better. Unfortunately, the factory down pipe in the N55 is quite restrictive, which results in slower exhaust gases and slower turbo spool. The Active Autowerke F-Chassis N55 Signature down pipe utilizes 3.5” diameter stainless steel piping in order to provide more power, quicker spool, and extreme durability. 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. 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.

A larger down pipe relieves some of this pressure, resulting in quicker and more efficient spool. With Active Autowerke's Signature downpipe, your N20 can rev quicker, and deliver more horsepower and torque. Minimizing back pressure while remaining daily drive-ability was the goal of our N20 downpipe. Owners can now upgrade to a product that is affordable, reliable, and easy to install. After months of research and development, our engineers settled on a 3.5 diameter pipe which utilizes the least number of bends possible. However, the Signature N20 down pipe still fits easily into the OEM location, with a painless installation process. Constructed entirely from 304 stainless steel with 1.5MM wall thickness, we are confident that you'll be pleased with how robust and durable this down pipe is. Trouble-free installation and a long lifespan ensure that you'll enjoy many miles of performance with your N20!

For the owner of a flagship G-series M-car, Active Autowerke provides a "no-compromise" performance upgrade that prioritizes both power and daily-driver refinement. These downpipes feature integrated GESI G-Sport catalytic converters, which are EPA-registered and fully OBD2 compliant. Utilizing proprietary precious metal loading, these converters reach operational efficiency within just 9 seconds of startup, drastically reducing emissions and eliminating the pungent exhaust smells common with aftermarket pipes. Designed as a direct bolt-on replacement, this system preserves your car's sophisticated electronics while providing a deep, aggressive V8-like growl that the S58 engine was always meant to have. Key Features: Refined Exhaust Note: Increases the volume and depth of the exhaust tone while maintaining a drone-free cabin. Fast Catalyst Light-Off: Proprietary loading technology ensures emissions systems satisfy factory monitors quickly. Corrosion Resistance: High-grade T304 stainless steel substrate is furnace-braised to the mantle for outstanding durability. Precision Casting: Casted upper flanges provide superior strength compared to standard cut-and-weld alternatives. Warranty Protected: Covered by a 5-year/50,000-mile structural warranty and a 2-year/25,000-mile catalyst core warranty.* Specifications: System Type: Twin Catted Downpipes Weight Reduction: Significantly lighter than the heavy ceramic factory assemblies Flow Rating: Engineered for engines producing up to 850 HP Hardware: Includes lower mounting brackets and precision V-bands Manufacturing: Hand-fabricated in the USA Vehicle Fitment: * 2021+ BMW M3 Sedan (G80) / Competition / xDrive 2021+ BMW M4 Coupe (G82) / Competition / xDrive 2023+ BMW M2 (G87) *Important Note: The catalyst warranty is void if the vehicle is equipped with an "aggressive burble" tune, as excessive backfire can physically degrade the catalyst core over time.

Unleash the Beast: Active Autowerke Signature GESI High-Flow Downpipes The S63 and N63 twin-turbo V8s are world-class engines, but they’ve got a breathing problem. From the factory, your BMW X5M, X6M, 550i, or 650i is suffocating under massive backpressure caused by restrictive, bulky catalytic converters. If you want real power, you have to let those turbos spin. Active Autowerke’s Signature High-Flow Downpipes are the ultimate "no-compromise" upgrade. Hand-fabricated in Miami, these 3.0" downpipes utilize GESi G-Sport Ultra High Output technology. You get the raw performance of a track setup with the refined, odorless experience of a street car—and most importantly, no Check Engine Light. Why These Downpipes Belong on Your BMW: Turbo performance is all about the pressure differential. By clearing the path behind the turbine wheel, you allow the turbos to work significantly less to produce significantly more. Turbo Response: Experience a massive reduction in lag with quicker spool-up and instant throttle tip-in. Massive Power Ceiling: The 4.5" GESi 400-cell cores are rated for 500hp to 850hp, ensuring they won't become a bottleneck as you climb the ladder of modifications. Clean & Odorless: Forget the "gas station" smell of catless downpipes. These proprietary precious-metal catalysts keep the air clean and your cabin comfortable. Hand-Built Precision These aren't mass-produced units. Each set is TIG-welded 304 stainless steel with cast upper V-band flanges for a factory-perfect seal. Because Active Autowerke builds these in-house, the fitment is surgical—no "massaging" or welding required for a secure bolt-on install. Turner Fitment Note: To guarantee 100% accuracy for your build, please provide your VIN at checkout. Note: These are F-chassis specific; G-body vehicles with the N63B engine require a different configuration. Core Features: No CEL Guarantee: Optimized for catalytic efficiency to keep your dashboard clear. 49-State Legal: EPA Registered and fully OBD2 compliant (Excludes CA). Built for Heat: Rated to withstand up to 1,500°F and reaches operational efficiency in just 9 seconds. Legendary Durability: 304 stainless substrate is furnace-braised to the mantle for maximum vibration resistance. Warranty Protected: Includes a 5-year/50,000-mile structural warranty and a 2-year/25,000-mile catalyst core warranty.* Technical Specs: Material: TIG-Welded 304 Stainless Steel Tubing: Full 3.0" (76mm) Mandrel-Bent Piping Catalyst: GESi Ultra High Output (400 CPI) HP Rating: 500hp - 850hp Lead Time: Custom made-to-order (Approx. 2 weeks) *A Note on Burble Tunes: We love a good exhaust crackle as much as anyone, but "aggressive" burble or pop maps physically destroy catalytic substrates. Use of such tunes will void the warranty on the GESi core.
