ARM Midpipes for BMW M850i

Overview

The ARM N63TU3 Midpipes will unleash the sound of your 4.4L Twin-Turbo BMW by upgrading both sections of the the OEM N63TU3 midpipes with a straight-piped, free flowing exhaust solution. The ARM N63TU3 Midpipes replace the OEM midpipes which have a middle muffler and hide the incredible sounds of the N63 engine. Below are sound clips of the ARM N63TU3 Midpipes paired with the ARM N63 Downpipes, an exhaust setup that will transform the sound of your N63-powered BMW!

If you already have ARM N63 Downpipes and are looking to increase the sound of your BMW even more, the ARM N63TU3 Midpipes are the perfect solution. It will give a noticeable increase in volume and tone over the ARM N63 Downpipes alone. Even the OEM burbles are significantly more audible with the valves open. If you want to retain the OEM downpipes, but desire more enthusiasm in your exhaust note, the ARM N63 Midpipes will liven up your exhaust sound without the need to replace your downpipes. In either setup, by keeping the OEM N63 axle back sections means you don't have to worry about deleting the OEM valve control. Allowing you to switch between an open-valve operation for maximum volume, or closed-valve quiet for moving through quiet neighborhoods.

As shown in the diagram above, the ARM N63TU3 Midpipes will replace the middle section of the exhaust, between the downpipes and the axle back section. By retaining the OEM axle back section the original function of the OEM exhaust valves are still retained. Giving you the option to drive around in "Comfort" mode with the valves closed, or switch to "Sport" or "Sport +" to unleash all the sounds of your N63!
