034 Motorsport Res-X Resonator Delete – Audi B9 A4 / A5 / ALLROAD

The 034Motorsport Res-X Resonator Delete unleashes a throaty growl that exudes the sound of performance and warns bystanders that this isn’t your average 4-cylinder. The new aggressive exhaust note is accomplished by removing the heavy factory resonator and replacing it with a ready-to-install 034Motorsport Res-X Resonator Delete.

No welding required! This is a true bolt-in exhaust upgrade that eliminates the quiet factory resonator for a deeper exhaust growl.

Enjoy a more aggressive exhaust note with no noticeable drone inside the cabin at a fraction of the cost of more expensive cat-back systems.
