3.5-Inch 304 Stainless Steel Valved Performance Exhaust System for Audi RS4 B9 & RS5 B9 2.9T
Upgrade your Audi RS4 B9 or Audi RS5 B9 2.9T with this complete 3.5-inch front pipe and valved cat-back exhaust system, designed to deliver increased exhaust flow, a deeper tone and a significantly more aggressive exhaust sound from the 2.9L twin-turbo V6.
Manufactured from high-quality 304 stainless steel, this Audi RS4 / RS5 performance exhaust offers excellent durability, corrosion resistance and long-term reliability while providing a larger and freer-flowing exhaust path compared with the factory system.
The upgraded 3.5-inch exhaust design helps reduce restriction through the exhaust system, making it particularly suitable for tuned and higher-output Audi RS4 B9 and RS5 B9 2.9T applications where improved exhaust flow is beneficial.
Integrated electronic exhaust valves allow you to control the sound whenever you want. Using the included remote controller, the valves can be closed for a quieter and more refined exhaust note or opened at the press of a button for a louder, deeper and more aggressive 2.9T V6 exhaust sound.
This Audi RS4 B9 / RS5 B9 valved performance exhaust combines larger-diameter pipework with adjustable sound control, making it suitable for both everyday road use and performance-oriented builds.
The system includes upgraded front exhaust pipes, full cat-back pipework, valved rear mufflers and exhaust tips for a complete performance exhaust upgrade.
The exhaust is designed for plug-and-play installation using the supplied clamps and factory mounting locations, with welding normally not required.
Professional installation is recommended.
