Audi A4 B9 Resonator Delete

Audi A4 B9 front resonator delete. Besides the res delete, the car is stock. The Audi A4 B9 exhaust system consists of the:  engine - cat - front res - mid res/muffler - dual mufflers. I deleted the front res. This setup has no drone while cruising and you can really only hear the sound while accelerating from 2,500-3,000 RPM's (higher RPM ranges). I would recommend this setup to anyone who wants a more aggressive tone from their A4 without drone or without it being too loud.
