DESIGN DETAILS
BOLD, REFINED, ENRICHED
The popular 2015-2020 VW Golf R and Audi S3 is begging to be unleashed with the precision-engineered iE Catback Exhaust System. This bolt-on upgrade delivers a unique deep rumble at low revs and an aggressive roar at high RPMs. Our proprietary DroneTrap technology eliminates unwanted drone, leaving only the perfect exhaust rumble. The factory valve electronics integrate seamlessly, giving you full control to switch between subtle and rowdy modes. Finished with quad 4” slash-cut tips for true motorsport style.
OVERSIZED QUAD TIPS
MAKE A STATEMENT
Make your Golf R or S3 stand out from the crowd with our quad oversized 4" exhaust tips. The aggressive slash-cut design and sleek brushed finish deliver a distinctive motorsport look bound to turn heads. Depth adjustability allows you to customize the tips to match your unique style.
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.
HEAR IT IN ACTION
YOUR STEREO IS OBSOLETE
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.

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.
