PROFILE

The ARM 4.0T Midpipes open up the incredible sound that your C7 4.0T powered Audi is capable of making!  The ARM 4.0T Midpipes replace the factory resonated midpipe section with a straight pipe to allow more of the 4.0T exhaust note to be heard.  The ARM 4.0T Midpipes were designed to match up perfectly to either the OEM downpipes and catback section, or to upgraded downpipes and catback section that connect to the OEM midpipes.  These 4.0T Midpipes are a direct replacement, they require absolutely no cutting or welding for a proper installation.  The ARM 4.0T Midpipes do not effect emissions and they will not cause a CEL.

 

CONSTRUCTION

 The ARM Motorsports 4.0T Midpipes are comprised of 304 Stainless Steel.  The stainless steel tubing measures 60mm OD to line up perfectly with downpipes or catback exhausts that connect to the factory midpipes. They incorporate an OEM style flex section to reduce torsion on the downpipes and turbos during hard acceleration, cornering, and braking. 


The ARM 4.0T Midpipes are designed with OEM style connection points at the downpipe and the catback sections.  The downpipe connection uses a OEM style 3-Bolt flange to allow it to mate up easily to either the OEM downpipes, or to upgraded downpipes that have a factory style flange.  



The catback connection is designed to bolt up to the factory sleeve clamp.  This makes the ARM 4.0T Midpipes compatible with either the OEM exhaust, or any upgraded exhaust that can connect to the factory midpipes.

Unlike lower-grade materials, 304 stainless ensures long-term reliability under extreme heat and boost pressures, making it ideal for high-performance applications. The precision-engineered tubular design is optimized for maximum exhaust flow, reducing backpressure and enhancing turbo efficiency. This manifold is similar to ones being sold on AliExpress and other overseas markets. However, we've partnered directly with the manufacturer to provide these manifolds in the highest of quality. Unlike those that are drop-shipping similar manifolds from unreliable sources. You are purchasing directly from the source.
