PROFILE
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!
CONSTRUCTION
The ARM N63TU3 Midpipes are a complete midpipe system which connects to the OEM axle back section to retain the OEM valve controls and exhaust tips.
The ARM N63TU3 Midpipes come in two main sections, the front section and the rear section. The front section connects to the downpipes which utilize the slip-fit style connection. 
The rear section of the ARM N63TU3 Midpipes connect to the front section using a slip-fit connection. The rear section then connects to the OEM axle back section of the exhaust using slip-fit connections which allow you to retain the OEM rear mufflers and valves.
If you're looking to increase the volume of your BMW M850i without needing to replace the downpipes, while retaining the OEM valved system, the ARM M850i Midpipes are the perfect solution for you. If you want to maximize the volume of your N63TU3, add the ARM N63 Downpipes to unleash a truly remarkable sound from your 4.4L V8 Twin-Turbo!
