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 mid-pipe 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 connects to the OEM mid-pipes.  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 affect 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 mid pipes. 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 an 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.
