The ARM Motorsports Audi 4.0T Midpipes are a direct-replacement midpipe set for the C7 and C7.5 Audi S6, S7 and RS7 with the 4.0T V8. They swap the factory resonated midpipe section for a straight pipe so more of the 4.0T exhaust note can be heard, and ARM says they do not affect emissions or cause a check engine light. The pipes are TIG-welded 304 stainless steel tubing measuring 60mm OD, with an OEM-style flex section and OEM-style connections at both ends. They bolt to the OEM or upgraded downpipes through a 3-bolt flange and to the factory sleeve clamp at the catback, and ARM says no cutting or welding is required.
