ARM Motorsports Audi 4.0T Midpipes - S6 S7 RS7 S8 A8/L

The ARM Motorsports 4.0T Midpipes are designed to unlock the deep, aggressive sound potential of the Audi 4.0T V8 found in the C7 and D4 platforms. The factory resonated midpipes significantly quiet the exhaust, limiting the character and presence of the engine. The ARM Midpipes replace this resonated section with straight-through 60 mm stainless steel tubing, allowing more of the engine’s natural tone to be heard while maintaining smooth exhaust flow.

These midpipes are engineered as a 100% direct replacement for the factory midpipe section—no cutting, trimming, or welding required. They bolt directly to factory downpipes using an OEM-style 3-bolt flange and connect to the rear exhaust using the factory sleeve clamp. This ensures full compatibility with OEM downpipes, OEM catback systems, or any aftermarket exhaust designed to mate with the factory midpipes.

Constructed from high-quality 304 stainless steel, the midpipes offer excellent durability, corrosion resistance, and long-term reliability. An integrated flex section helps reduce drivetrain-induced stress during acceleration, cornering, and braking, protecting both downpipes and turbochargers.

With a straightforward 45-minute installation, the ARM 4.0T Midpipes provide an immediate improvement in sound and flow without requiring modifications to surrounding components.
