NEW ECS C8 RS6 / RS7 Race Cat-Back Exhaust System

For this exhaust system, our goal was simple: amplify the exhilarating 4.0T exhaust note with a proper "straight pipe" cat-back exhaust system. To accomplish this goal, our engineers started by incorporating full 3" piping from downpipes to tips. We specifically designed this catback with flow in mind to ensure the exhaust would never be a restriction. Compared to the OEM 2.5" diameter exhaust piping, the 3" ECS Race Cat-Back offers a significant increase in exhaust flow and expedited exhaust gas expulsion. For exhaust construction, high-quality 304 Stainless Steel was used to ensure long-term corrosion resistance, durability, and weight reduction. Next, an optimized x-pipe was added to aid in exhaust scavenging. This x-pipe further improves the flow of this system and results in substantial horsepower and torque gains. Black chrome RS-style oval exhaust tips are included with the exhaust for OEM+ styling and precise fitment inside the factory diffuser.
