Take your N54 powered BMW 335xi to the next level with ARM Motorsports 3" catless downpipes.
The ARM N54 AWD catless downpipes eliminate the restrictive OEM converters on the stock downpipes allowing the exhaust to flow more freely, increasing power and torque. Because higher boost levels generate more heat, the ARM 335xi catless downpipes allows your AWD N54 to run boost settings of Stage 2 tunes and beyond.
The ARM 335xi catless downpipes are designed with 3" stainless steel construction to optimize exhaust flow off the turbochargers and reduce to 2.5" to match up perfectly to the OEM midpipes. Our 335xi downpipes are designed specifically to fit your AWD N54 platform.
Each downpipe has two O2 sensor bungs so the factory BMW O2 sensors can be remounted allowing the ECU to continue to monitor the air/fuel mixture via the exhaust. Because these downpipes are a catless design, an ECU tune or CEL fix will be needed to avoid a CEL from displaying on instrument panel.

Bang for buck! Came with hardware and gaskets!
First off, the reach out from the arm team was top notch, the shipping was pretty amazing, super quick. Came packaged like it was a baby being delivered. The product was perfect. Fitment was perfect. All around no complaints. Just know if you are doing awd down pipes, pro tip. Remove 02 sensors remove both motor mounts and remove subframe bolts. Rear turbo downpipe off first then putting back together. Leave the 02 sensors out. Install the front turbo down pipe the. The rear turbo downpipe. For the v band I used a clamp pliars that I got from AutoZone.
Came extremely quick. Came as described. Amazing packaging. Great service. Thank you.
My experience was very good with ARM. When I had a problem, they were right there to make it right simple, fast and effective. I am going to refer all of my friends to this company for their upgrade and tuning needs. I will be purchasing from ARM again myself!!!
awesome upgrade and amazing sound once completed! Be sure to order replacement clamps and pre cat gasket, old ones tend to rust overtime.
