N63 Midpipes 2.75" Exhaust System

The ARM Motorsports N63 Midpipes are a performance exhaust component engineered to amplify the sound of your BMW's N63/N63TU 4.4L V8 engine. These midpipes replace the factory section, which typically includes two resonators and a center muffler that can muffle the engine's aggressive tone. By deleting these components, the ARM N63 Midpipes provide a noticeable increase in exhaust volume and a richer tone, especially when paired with performance downpipes. They feature a slip-fit connection between the front and rear sections for ease of installation and integrate with the factory exhaust hangers for a secure fit. A key design element is the utilization of OEM exhaust valves, allowing drivers to retain full control over their exhaust note. This means you can enjoy a quieter ride in Comfort mode with the valves closed or unleash the full roar of the N63 engine by opening the valves in Sport or Sport+ modes. The ARM N63 Midpipes are designed to seamlessly connect to the OEM axle back exhaust sections, ensuring compatibility with original rear mufflers and tips. They are compatible with OEM N63 slip-fit downpipes or ARM N63 Downpipes. For vehicles with earlier 2-bolt downpipes (Pre-2012), conversion to a slip-fit style connection is possible by also ordering the ARM N63 Downpipes. This product requires the ARM N63 Downpipes to fit properly. It is listed for Off-Road Use Only and is intended for racing vehicles. The ARM N63 Midpipes are backed by a lifetime warranty against defects in craftsmanship and fitment.
