Description
The APR Catback Exhaust System for the Audi C8 RS6 and RS7 is a complete, high-performance exhaust solution engineered to replace the entire exhaust system from the factory catalyst back. Designed to enhance power, sound, and aesthetics, this system delivers a true motorsport-inspired driving experience while maintaining refinement for everyday use.
This system is built to improve exhaust flow through smooth transitions, oversized piping, straight-through mufflers, and optimized resonator design. The result is a significant performance increase, sharper throttle response, and a more aggressive exhaust tone under load. It also provides a refined cruising experience with reduced drone when needed.
Constructed from premium T304 stainless steel, the system features mandrel-bent tubing, TIG-welded joints, and a brushed finish for maximum durability and corrosion resistance. Precision-engineered brackets and OEM-style slip clamps ensure accurate alignment and straightforward installation without modification.
The exhaust system incorporates a dual-path design with valve control functionality. When the valves are open, exhaust gases flow freely through a dual 3-inch (72mm) system for maximum performance. When closed, gases are redirected through a quieter 2.5-inch (63.5mm) path for reduced volume and improved daily drivability. An integrated Helmholtz resonator further minimizes unwanted drone frequencies without restricting high-flow performance.

At the rear, the system finishes with oversized RS-style diamond black oval exhaust tips measuring 8.23 x 4.76 inches (211 x 121mm), featuring a subtle APR logo for a premium, factory-plus appearance.
This system delivers an estimated gain of 9 horsepower and 16 ft-lbs of torque to all four wheels, making it a substantial performance upgrade while maintaining full emissions compliance for worry-free use.
