DroneTrap Technology
IE’s advanced DroneTrap resonator technology targets and cancels drone frequencies by redirecting and tuning pressure waves through a mathematically engineered chamber. The result is a refined, aggressive exhaust note without the harsh in-cabin resonance common in other aftermarket systems.
Factory Valve Control Integration
The IE catback integrates seamlessly with the factory exhaust valve system. Maintain your Audi Drive Select functionality, switching between quiet and aggressive exhaust tones with the push of a button—no tuning or modifications required.
Built for Durability
Engineered with long-term reliability in mind, this exhaust system uses corrosion-resistant T304L stainless steel tubing, hand TIG-welded at all joints for strength and precision. The large stamped muffler body resists heat-related warping, while reinforced hanger mounts ensure the system stays securely in place, even under spirited driving.
