APR Catback Exhaust System - Audi RS6/RS7 (C8) - Dual 3in
APR builds its exhaust systems around real gains in flow and sound control, not just noise for the sake of it, and this catback for the Audi RS6 and RS7 is no exception. SKU CBK0050 upgrades the entire rear section to a dual 3in (72mm) path for improved flow when the valves are open.
This listing covers the Audi RS6 Avant (C8, 4K) and Audi RS7 Sportback (C8, 4K). The system uses a valved design, with a smaller 2.5in (63.5mm) sound reduction path active when the valves are closed for a more civilised note around town.
Key Features
- Dual 3in (72mm) mandrel bent exhaust path
- Multichambered rear muffler and resonator with Helmholtz resonator to reduce drone
- Valve controlled sound reduction path via 2.5in (63.5mm) piping when closed
- Oversized 211mm x 121mm (8.23in x 4.76in) RS style oval exhaust tips
- Diamond black tip finish with subtle APR logo
