The CTS Turbo resonator delete kit is designed for Audi A4, A5 and Allroad B9/B9.5-generation vehicles. It replaces the original resonator in the factory front resonator pipe with a more free-flowing section.
Installation adds a subtly louder and deeper exhaust note without droning or unpleasant resonance. The kit does not trigger the check engine light (CEL) and is compatible exclusively with the factory front resonator pipe. Suitable for front-wheel-drive and quattro all-wheel-drive versions.
Features
- Replaces the factory resonator on the original front resonator pipe.
- Made from durable T304 stainless steel.
