ENRICHED SOUND
DRONETRAP
WITHOUT DRONE

IE's advanced DroneTrap technology captures the pulse waves responsible for the V8 engine's exhaust note and draws them into dual mathematically tuned resonators. The internal ports are engineered to resonate these waves against each other in a process that selectively cancels out those responsible for annoying drones. The remaining waves produce the deepened and enriched exhaust acoustics you love.

Our catback design includes all sections to replace the factory exhaust tips, mufflers, tailpipes, center pipes, x pipes, and midpipes all the way up to the stock CATs/downpipes. Enjoy an entirely new exhaust system that delivers the perfected exhaust note from your 4.0T engine.

Advanced 3D scanning tools and cutting-edge software provide our engineers with a high-resolution digital model of the Audi C8 RS chassis. This data is then used to maximize the exhaust size for flow and optimize all available space for the perfect catback fitment.
