Description

The APR Catback Exhaust System is designed as a complete, high-performance exhaust upgrade for the Audi B9 RS4 and RS5. Constructed from durable T304 stainless steel, this system includes a 3.5-inch midpipe and Helmholtz resonators to optimize exhaust flow and sound. It aims to provide an aggressive yet refined performance sound, complementing the powerful nature of the RS4 and RS5. Compatibility is confirmed for the Audi B9 RS4 and RS5 from model years 2018 through 2025. Some B9.5 vehicles may have specific equipment that should be reviewed for fitment.
