APR Catback Exhaust System with Center Muffler for Audi 4.0 TFSI - C7 RS6 and RS7
The APR Catback Exhaust System personalizes your sound and performance. Beautifully hand-crafted T304-stainless-steel components adorn the system with stunning TIG-welding throughout. Our straight-through brushed-finished mufflers smooth the exhaust note to a deep growl, without adding restrictions. Strong high-quality bracketry and OEM-style clamps hold the system steadily in place, making the install or removal a snap, and fitment simple, yet precise. Cast 2.75” to dual 2.5” rear splitter creates an ultra-smooth transition, steadily feeding exhaust gasses out of the system. Our cast valve housings enable the vehicle to be fitted with the factory electronic valve actuators, retaining OEM valve operation. An optional center muffler / Center muffler delete is available.

Aperçu du système
Notre système d'échappement utilise des tuyaux plus grands par rapport au système d'échappement d'origine, mais pèse moins dans la configuration de base. Nous utilisons des tuyaux doubles de 2,75" de diamètre extérieur, qui se divisent ensuite en un design quadruple de 2,5". Le système d'origine utilise des tuyaux de 2,375". Le système ci-dessous comprend le silencieux central optionnel.
Mufflers
The mufflers are responsible for reducing the exhaust note and do so without adding unnecessary restrictions to the system. Each unit features two straight-through perforated tubes that are tightly wrapped with stainless steel and fiberglass material. With the valves closed, the system is tamer, but once opened, the system sounds deep, throaty and aggressive! The mufflers have a beautiful brushed finish, and are tucked high in the exhaust tunnel, making them perfect for lowered vehicles and a treat to see when looking at the vehicle from the rear.
The optional front muffler is responsible for reducing sound volume further. This configuration is recommended for customers who have our Race DPs and want a tamer exhaust note.
Cast Splitter
We cast the rear muffler splitters to maximize the system’s performance by keeping exhaust velocity high and back pressure low. This is accomplished by gradually splitting the system from a single 2.75” pipe to dual 2.5” pipes. The organically shaped casting allows us to make this transition gradually as to not disturb the flow of gasses.
Exhaust Valves
Our system features two valves that allow control of the volume of the system via the factory exhaust valve actuators. In doing so, the system can go from tame to aggressive instantly! Unlike pneumatic systems, and other common valves found in the market today, our system maintains identical OEM operation all the way down to the factory valve actuation angles. Furthermore, the system is compatible with aftermarket exhaust remotes, allowing end users to manually open the system at the click of a button.
We cast the valve housings out of T304 stainless-steel. Internally the system uses CNC-machined T303 components and brass bushings, which have stood up to our extreme torture testing. All necessary hardware is welded into place and is designed to combat heat and vibration for years to come.
Brackets
Our brackets ensure a strong and precise fit, every time. With our design, you’ll never need to worry about the brackets sagging and losing their shape over time, or the post slipping out of the hangers. The brackets are rigid, exact in their position, fit snugly in place and are made to stand the test of time.
Tubing
We use T304 stainless steel tubing throughout. We brush and de-burr all pipes, use mandrel bending techniques to ensure the pipes keep a constant diameter throughout, and use argon-back purged TIG welding for a strong and attractive weld.
Tips
The factory exhaust tips are integrated into the rear bumper valance. APR retains this layout and places the exhaust outlets within, making the system compatible with factory and aftermarket tips.
Tunnel Brace
The factory stamped steel tunnel brace leaves little to be desired. We’ve redesigned ours to sit slightly lower in the tunnel to allow for larger exhaust tubing. As an added benefit, the CNC-bent laser-cut brace adds additional structural rigidity to the chassis!
Clamps
Our system uses OEM-style low-profile slip clamps. Our clamp selection allows the system to sit high in the exhaust tunnel, as is favored by lowered vehicles, with ultimate compatibility no matter what DP you may have. The clamps make for easy swapping of the mid section, and slide out of the way to make adding or removing a Race DP easy. Each connection point is strategically placed to ensure the system has minimal opportunity to rotate during install or during years of heavy driving.
DP Compatibility
We’ve designed our system to be 100% bolt-on with the factory exhaust DP and APR Race DP.
