TNEER Valvetronic Exhaust System for Audi RS6 (C7) 2013-2018
The Audi RS6 C7 is built around a front-mounted 4.0-litre twin-turbocharged V8 producing 560 horsepower, the EA824 engine with cylinder deactivation technology that shuts down four cylinders under light load. The RS6 Avant's combination of a high-output twin-turbocharged V8 and a full-size estate body creates a platform that occupies a unique position in the performance car market, delivering supercar-level performance within a practical load-carrying body that no comparable alternative has matched. The C7's front-engine all-wheel drive architecture and extended Avant body create exhaust routing requirements specific to this platform, with extended primary runs through the transmission tunnel and underbody of the long-wheelbase estate body demanding precise tube geometry across the complete system length. TNEER engineers this complete valvetronic system specifically for the RS6 C7, addressing the full exhaust path from the front pipe through the mid pipe to the valvetronic rear mufflers in a single cohesive system built from high-grade stainless steel throughout.
Each section is formed from single-piece high-grade stainless-steel tubing using robotic pipe bending technology, producing continuous tube geometry throughout the complete system without the weld joints and flow disruptions of multi-segment construction. The front pipe addresses the primary exhaust path from the EA824's manifold outlets, establishing the flow characteristics that carry through the remainder of the system. The mid pipe continues that routing through the underbody to the valvetronic rear muffler section, maintaining consistent internal diameter and eliminating the flow disruptions that welded multi-segment construction introduces across the extended Avant underbody layout. The system installs to all factory mounting locations, requiring no structural modification and maintaining correct chassis alignment throughout.
The ECU-controlled valvetronic rear mufflers manage acoustic output through the RS6's existing drive mode architecture without secondary controllers or aftermarket modules. Valves closed, the system maintains a composed tone appropriate for road use and the RS6's broad daily operating profile while presenting more of the twin-turbocharged V8's character than the factory exhaust allows at any throttle position. Valves open, the full acoustic output of the EA824's 4.0-litre twin-turbo V8 is unobstructed and responds directly to throttle input and engine speed. On a platform where the factory exhaust manages the V8's acoustic character to suit both full-throttle acceleration and cylinder deactivation cruising, the distinction between the factory output and the valvetronic system with valves open is immediate and significant on every drive.
Optional Race Downpipe:
For owners who want to address the primary restriction point in the exhaust path, TNEER offers race downpipes that deliver meaningful performance and acoustic improvement beyond what the front pipe, mid pipe, and valvetronic muffler system alone provides.
- The race downpipes remove the factory catalytic converters immediately downstream of the turbocharger outlets, where back pressure reduction has the most direct effect on turbine behavior, spool characteristics, and mid-range torque delivery. On the EA824's twin-turbocharged V8 at 560 horsepower, the relationship between downstream restriction and turbocharger efficiency is immediate and measurable at every point in the rev range. For a platform producing this level of output in an estate body, the performance gains from race downpipe installation are consistent with the RS6's position as one of the most capable all-round performance cars of its generation. These components are intended for closed course and off-road use.
All downpipe components are fabricated from high-grade stainless steel and engineered to the same fitment standard as the remainder of the complete system.
About TNEER:
TNEER is built around a single engineering conviction: the exhaust system is not a peripheral component. It is the primary interface between the engine and the driver's experience of it. Every system TNEER produces is developed to bring out the true voice of the engine it is built for, improving exhaust flow and delivering a distinct tone that is mechanical, raw, and directly connected to the character of the car.
The manufacturing process that defines TNEER's fitment standard is their high-tech robotic pipe bending technology. Rather than fabricating exhaust routing from multiple welded sections, TNEER forms each tube from a single continuous piece, bending high-grade material to navigate the spatial constraints of each specific engine bay without the diameter reductions, flow disruptions, and structural inconsistencies that welded multi-piece construction introduces. The result is an exhaust system with continuous tube geometry, perfect fitment to the platform it is built for, and no compromises in the routing that precision bending makes unnecessary.
For enthusiasts who regard sound and performance as inseparable elements of the driving experience, TNEER engineers each system to deliver both from the first throttle input.
Note:
- Downpipes are not CARB certified and may not be legal for use on emissions controlled vehicles; intended for off road use only.
- ECU tuning may be required due to removal of factory catalytic converters.
