DRONE TRAP

iE's advanced DroneTrap technology captures the pulse waves responsible for the 2.0T engine's exhaust note and draws them into a mathematically tuned resonator. The internal port is 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 deep and enriched exhaust acoustics enthusiasts love.

BUILT TO ENDURE - QUALITY IS IN THE DETAILS

iE’s catback exhaust is built for sound, durability, and reliability. Made from mandrel-bent T304L stainless steel, it resists corrosion, with hand TIG-welded joints ensuring lasting strength. A stamped multi-wall muffler prevents warping, while reinforced hangers keep everything securely mounted. Bridged piping boosts strength and disperses weight to reduce stress and vibration. Inspired by high-end OE designs, wide-width stretch clamps keep every connection tight and leak-free.

SOUND CONTROL - SEAMLESS FUNCTIONALITY

Control your exhaust volume through the factory drive select controls from your MMI system. Select comfort to drive around your suburb like a civilized neighbor, or trigger Sport/Dynamic mode to release that boosted roar.

EXHAUST VALVES - REFINED TO ROWDY

In Comfort/Normal mode, the valves stay closed, routing all exhaust through the center-mounted muffler to reduce volume while keeping a sporty tone. Switch to Sport/Dynamic mode to open the valves, bypassing the muffler through twin 2.5" pipes for a loud, performance rumble.

INSTALL GUIDE - AVERAGE INSTALLATION TIME: 1 HOUR

Install your new Catback Exhaust kit without any permanent modifications or installation hassles. The install process is straightforward with basic tools, however, an autolift is highly recommended.

ADVANCED R&D - ENGINEERING THE PERFECT FIT

3D scanning and cutting-edge software give our engineers a high-resolution digital model of the VW/Audi MQB chassis. This data allows us to maximize exhaust flow and optimize every inch of available space, ensuring a perfect fit with no rattles or rubbing.
