How to install ARM downpipes on BMW e90 n54 xdrive 335xi and reviewed
I couldn't find anything on YouTube on downpipes for my specific car, this takes you step by step with myself and the owner of track days tuning through the process. It took us about 2 and a half hours. So I can imagine its possible to get it done at home. Just be sure you have the car up high enough, and you have ALL the right tools. Fitment and review is at the end! Enjoy the video and enjoy the mod! Link to the downpipes- put PLUS10PSI @checkout for 10% off https://www.armmotorsports.com/collec...
