Portable 034motorsport Res-x Resonator Delete - Audi S4 And S5 Sportback B8/b8.5 - 3.0t Series [K8bDULWC]

The 034Motorsport Res-X Resonator Delete and X-Pipe unleashes a throaty growl and exotic tone that exudes the sound of performance and warns bystanders that this isn't your average family sedan. 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 and integrated X-Pipe.

No welding required! This is a true bolt-in exhaust upgrade that eliminates the quiet factory resonator for a deeper and more aggressive exhaust note, and the incorporated X-Pipe works to balance exhaust pulses from each side of the motor resulting in smoother exhaust flow.

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.
