Performance Valved Cat-Back Exhaust System for Audi RS4 B8 & RS5 B8 4.2 FSI V8
Upgrade your Audi RS4 B8 or Audi RS5 B8 4.2 FSI V8 with this complete full valved cat-back exhaust system, designed to deliver a deeper, louder and more aggressive V8 exhaust note while retaining full control over the sound when required.
Manufactured from high-quality 304 stainless steel, this performance exhaust system offers excellent corrosion resistance, durability and long-term reliability. The freer-flowing cat-back design helps reduce exhaust restriction while allowing the naturally aspirated 4.2 FSI V8 to produce a much stronger and more distinctive exhaust tone.
The integrated electronic exhaust valves allow you to switch between two different sound characters. Using the included remote controller, the valves can be opened or closed at the press of a button — keep them closed for a quieter and more refined exhaust note, or open them for the full aggressive V8 sound.
This Audi RS4 B8 / RS5 B8 performance exhaust is ideal for drivers looking for more sound and character without permanently committing to an excessively loud exhaust. It works equally well for daily driving, spirited road use and performance-oriented builds.
The 304 stainless steel exhaust layout is designed to provide improved exhaust gas flow through the rear section while retaining a vehicle-specific fitment for the Audi RS4 B8 and RS5 B8 4.2 FSI.
The system is designed as a plug-and-play cat-back exhaust upgrade using the supplied clamps and factory-style mounting locations, with welding normally not required.
Professional installation is recommended.
