    PROFILE

    Take your N54-powered BMW 335i to the next level with ARM Motorsports' 3" catless downpipes. 
    The ARM N54 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 catless downpipes allows your 335i to run boost settings of Stage 2 tunes and beyond. 

     

    CONSTRUCTION

    The ARM 335i catless downpipes are designed with a 3" stainless steel construction to optimize exhaust flow and obtain optimal back-pressure. Each downpipe has 2x O2 sensor bungs so the factory BMW O2 sensors can be remounted allowing the ECU to continue to monitor the exhaust gases. 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.

      Skip VRSF, get ARM

      I ordered a set of VRSF downpipes for my N54. That was my biggest mistake, however it is what lead me to find ARM. VRSF sent me a set of downpipes that had massive holes in the welds, a total lack of penetration on every weld (only the surface was welded), and there was no back purging on the welds (for you non-welders, that's very bad for stainless). I went through the process of trying to contact VRSF via phone and ended up on a very aggravating email chain. Finally they approved the return and refund. -I called ARM and the gentlemen that answered was beyond professional and helpful. He answered all my questions and even offered to pull a set of downpipes off the shelf to send meet photos of the welds, I declined the offer due to his confidence in their product quality. Upon receiving the ARM downpipes today I am happy to say that they are exactly what I hoped they would be. The pipe material is heavier/stronger, the welds are textbook, and the overall quality is hand crafted goodness that that you will not be disappointed in. BUY ARM.

      Downpipes

      Love the sound of my exhaust wish I would’ve went catless sooner. Definitely worth the money.

      Perfect

      Figment was perfect, only took about 3 hrs to install and that was in no hurry. Sounds sick with my muffler delete. Welds are amazing. Been waiting to do this mod for forever and I couldnt be happier. Goes great with the 5” stepper fmic.
