Description
The ARM N63TU3 Midpipes are designed to replace both the front and rear midpipes of the OEM exhaust system, eliminating the center muffler for a free-flowing, high-performance exhaust setup. With no welding required, these midpipes provide a noticeable increase in volume and tone, transforming the sound of your 4.4L Twin-Turbo N63 engine.
Whether you pair them with ARM N63 Downpipes or retain the OEM downpipes, these midpipes will dramatically improve the aggressiveness and clarity of your exhaust note. The factory exhaust burbles become more pronounced, and the deep, throaty tone of the V8 is fully unleashed.
Retains OEM Valve Control for Adjustable Sound
One of the standout features of the ARM N63TU3 Midpipes is their ability to retain the OEM exhaust valves, giving you full control over your exhaust volume and tone.
- With the valves closed, the system remains subtle and refined for comfortable driving.
- With the valves open, the exhaust note becomes loud, aggressive, and race-inspired, perfect for spirited driving.
This means you can switch between a quiet mode and a full-performance roar at the push of a button, making these midpipes an ideal upgrade for enthusiasts who want the best of both worlds.
Premium Construction & Direct Bolt-On Fitment
The ARM N63TU3 Midpipes are engineered for perfect fitment on the BMW M850i xDrive (G14 and G15 models). They are constructed from high-quality materials and designed for a seamless bolt-on installation with slip-fit connections, eliminating the need for welding.
The midpipes are divided into two sections for easy installation:
- Front section: Connects to the downpipes using a secure slip-fit connection.
- Rear section: Attaches to the OEM axle-back exhaust while maintaining factory mufflers and valve control.
This design ensures that your BMW retains its stock exhaust valve functionality, allowing you to adjust the sound based on your driving mode.
