For more information, visit www.P65warnings.ca.gov.The APR Catback Exhaust System (CBK0050) is the definitive high-performance exhaust solution for the Audi C8 RS6 and RS7. This is a true "catalyst-back" system, including downpipes that extend all the way to the factory catalysts in the upper engine bay. Engineered to unlock the full acoustic and performance potential of the 4.0T V8, this system delivers an aggressive growl at wide-open throttle and verified gains of 9 HP and 16 FT-LBS of torque to all four wheels.
The system features a massive dual 3-inch (72mm) mandrel-bent flow path. To ensure a premium driving experience, APR integrated a Helmholtz resonator that cancels drone frequencies without restricting airflow. The rear mufflers feature a dual-path design: when the valves are open, gases travel uninterrupted for maximum sound; when closed, gases are diverted through a civilized 2.5-inch sound-reduction path. The system is finished with gargantuan 8.23”x4.76” RS-style diamond black oval tips for a commanding presence.
