Product Details
The popular 2015-2020 VW Golf R and Audi S3 are ready to be transformed with the precision-engineered iE Catback Exhaust System. This bolt-on upgrade offers a unique deep rumble at low revs and an aggressive roar at high RPMs. Proprietary DroneTrap technology eliminates unwanted drones, ensuring a perfect exhaust sound. Factory valve electronics integrate seamlessly, allowing full control to switch between subtle and aggressive modes.
Quad 4” slash-cut tips add a true motorsport style, making any Golf R or S3 stand out. The aggressive design and sleek brushed finish provide a distinctive look that catches attention. Depth adjustability enables customization of the tips to match individual style preferences.
iE's advanced DroneTrap technology captures pulse waves from the 2.0T engine's exhaust note and channels them into a mathematically tuned resonator. The internal port is engineered to resonate these waves against each other, selectively canceling out those that create unwanted drones. The remaining waves produce deep, enriched exhaust acoustics that enthusiasts appreciate.
This catback exhaust is designed for sound, durability, and reliability. Crafted from mandrel-bent T304L stainless steel, it resists corrosion, while hand TIG-welded joints ensure lasting strength. A stamped multi-wall muffler prevents warping, and reinforced hangers secure everything in place. Bridged piping enhances strength and disperses weight to reduce stress and vibration. Inspired by high-end OE designs, wide-width stretch clamps maintain tight, leak-free connections.
Control exhaust volume through factory drive select controls via the MMI system. Comfort mode keeps the valves closed, routing all exhaust through the center-mounted muffler to minimize volume while retaining a sporty tone. Switching to Sport/Dynamic mode opens the valves, allowing exhaust to bypass the muffler through twin 2.5" pipes for a loud performance rumble.
3D scanning and advanced software provide engineers with a high-resolution digital model of the VW/Audi MQB chassis. This data maximizes exhaust flow and optimizes every available space, ensuring a perfect fit with no rattles or rubbing.
