RPM Performance Audi RS4 B8.5 Front Resonator Delete Kit

Transform the sound and character of your Audi RS4 B8.5 with this front resonator delete kit. Designed to replace the restrictive factory front resonators, this upgrade delivers a deeper, more aggressive exhaust note while improving exhaust gas flow and enhancing the overall driving experience.

Manufactured in Norfolk, UK from T304 stainless steel, each kit features precision CNC mandrel bent pipework to maintain optimal exhaust flow and performance. Finished in brushed stainless steel, the system offers a clean OEM+ appearance and exceptional durability.

The front resonator delete provides the perfect balance between everyday usability and enhanced performance sound. During normal driving, the exhaust retains its refined character with minimal increase in cabin noise, making it ideal for daily use and long motorway journeys. Under acceleration, however, the RS4's naturally aspirated V8 comes alive with a much sharper, more aggressive tone that truly unlocks the soundtrack the car deserves.

Designed as a simple fit upgrade specifically for the Audi RS4 B8.5, the kit installs easily using the supplied clamps with no welding required.

A simple yet highly effective upgrade for owners looking to unleash the iconic 4.2 FSI V8 soundtrack, delivering increased character and a more engaging driving experience while maintaining OEM levels of fit and quality.
