Our valved axle-back exhaust system for the BMW F30 335 or F32 435i gives you the versatility you want in an exhaust system. Valves open, you can let everyone know you're here - loud pipes save lives, right? Valves closed for when the kids or the dogs are sleeping in the back seat on a long road trip. Our valved axle-back system functions differently from other alternatives on the market, including the factory system; most of these we've found only utilize one side of the exhaust system for either valve closed or valve open operation. Accordingly, we designed our Turner valved axle-back to utilize both muffler exits for valve open and valve closed operation. We use beautiful 1.25mm thick, 80mm 304SS pipes with smooth mandrel bends to create our axle-back, ensuring that our systems are as visually appealing as they are audibly. We believe we've done the F30 335i and F32 435i the justice it deserves from an exhaust perspective - your turn to judge!

A new oxygen sensor can improve driveability and lengthen engine life. Ultimately, you achieve a smoother running engine that is more fuel efficient. Feedback from the oxygen sensor provides closed-loop control of the injected quantity of fuel for optimum air-fuel mixture, enabling virtually complete combustion to take place. Contaminants in gas and certain atmospheric conditions can drastically shorten the life of any oxygen sensor, therefore they should be checked with every periodic maintenance and changed if necessary.

This is the OEM Bosch oxygen sensor for BMW's with the N20 and N26 motors. This sensor is mounted in the catalytic converter in the rear most position. OEM replacement for BMW # 11787589122.

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!
