At Active Autowerke, it's not ONLY about making as much power as possible but to maximize the enjoyment of the drive. For 40 years, power has been the end result of improved performance due to our relentless desire to develop a refined, quality product. This philosophy behind our performance parts is best represented by one of the newest additions to our G2X/G3X BMW M340i and M440i collection. The Active Autowerke M340i/M440i rear exhaust was carefully engineered to eliminate the overly quiet sound of the factory M340i and M440i exhaust, while also allowing for optimum flow and resonance by reusing the actuator from the BMW valve. Every effort was made in addressing the not so appeasing sound of the stock OEM exhaust, but in designing an exhaust worthy for the BMW 'M' badge. We believe our rear exhaust offers the best combination of sound and performance versus other systems on the market today. Available for both models, this axle-back exhaust gives your BMW the deep, throaty, growl a car of its caliber should have had from the factory! Features: Made in the USA 304 Stainless Steel Low, Deep Sound with stock Valve Control Each exhaust test-fit on the M340i/M440i Exhaust Fixture Guaranteed to fit all G-series M340i and M440i Includes all necessary installation hardware

For over 30 years, Active Autowerke has been the one to turn to for high-quality BMW performance products. Committed to enhancing the performance of BMWs through the highest quality products is what Active Autowerke is all about. 

The B46 downpipes are strategically engineered to virtually eliminate the immensely restrictive characteristics of the factory downpipes – therefore reducing radiant heat and increasing performance.

Features Include

NO CEL when using this downpipe

GESI EPA registered high flow and fully OBD2 compliant

Casted upper stainless steel V-Band for precise fitment

3 inch diameter piping allows for maximum power output

Quicker turbo spool

Withstands up to 1500° F

Can reach operational efficiency within 9 seconds of startup

Easily bolts-on – no cutting or welding required

Durable construction from TIG welded 304 stainless steel

Ultra high flow 400 cell per square inch catalyst

EPA certified for use on OBD2 vehicles (1996 and newer) except in California

304 stainless steel substrate in catalytic converter is furnace braised to the mantle for outstanding durability

GESi® proprietary precious metal loading technology ensures greatly reduced emissions

Both passengers and drivers are safe from harmful emissions and noise

Precise fitment

Made in Miami, Florida

Covered by 5 Year / 50,000 Mile Warranty (on shell and tube ends)

FITMENT NOTE: For G-Chassis models (G20, G22), the cutoff build date of 08/2020 is important as cars produced after that date have a downpipe with different bracket locations. Cars with a build date of 08/2020 and earlier have the brackets in a V configuration and will need Active Autowerke p/n 11-065. Cars with a build date of 09/2020 and later have the brackets in a straight line and require Active Autowerke p/n 11-065G. If your car was built in the cutover months 08/2020 and 09/2020, please call in or email us your VIN so we can ensure you get the correct downpipe.
