CTS Resonator Delete Kit – B9/B9.5 Audi A4/A5/Allroad

Wake up the exhaust on your B9+ Audi A4, A5, or Allroad with a subtle, drone-free increase in sound — and no check engine light. This CTS resonator delete replaces the factory resonator on the stock front resonator pipe with a high-flow section, installs quickly with hand tools, and is completely reversible.

Features

• Replaces the factory resonator on the stock front resonator pipe with a high-flow section
• Adds a deeper note without replacing the whole exhaust
• More sound without added drone
• Durable T304 stainless steel
• Stainless steel exhaust band clamp
• Quick install with simple hand tools, completely reversible
• Compatible with the factory front resonator pipe only
