For more information, visit www.P65warnings.ca.gov.The APR Catback Exhaust System (CBK0010) is a premium, hand-crafted upgrade for the Audi C7/C7.5 RS6 and RS7. This system is engineered to provide a deep, powerful V8 growl while significantly reducing exhaust backpressure compared to the factory unit. Constructed from T304 stainless steel with argon-back-purged TIG welding, it offers a level of quality and durability that matches the caliber of the RS platform. The design features ultra-smooth cast splitters and straight-through mufflers to ensure maximum airflow without the rasp often found in lesser systems.
One of the standout features of the APR system is the inclusion of cast valve housings, which allow for the seamless reinstallation of your factory electronic valve actuators. This preserves the OEM "Drive Select" functionality, enabling the car to be quiet and refined for daily driving or aggressive and vocal when in Dynamic mode. Additionally, the kit includes a CNC-bent and laser-cut tunnel brace, which replaces the factory unit to provide increased chassis rigidity and proper clearance for the larger diameter piping.
Features:
- Full T304 Stainless Steel: High-grade, corrosion-resistant construction with a brushed finish for a premium look.
- Valved Design: Retains full factory control over exhaust volume using the original electronic actuators and cast valve housings.
- Optimized Flow: Features dual 2.75" mandrel-bent tubing that transitions through ultra-smooth cast splitters into quad 2.5" outlets.
- Straight-Through Mufflers: Sound-absorption technology delivers a deep V8 growl without performance-robbing baffles.
- Enhanced Rigidity: Includes a custom tunnel brace to ensure maximum chassis stiffness and a perfect, low-profile fit.
- Low-Profile Engineering: Specifically designed to maintain ground clearance on lowered vehicles.
- Easy Installation: A direct bolt-on system utilizing OEM-style slip clamps and Torca AccuSeal tip clamps.
