ProCore Catalyst Advantage
IE’s proprietary ProCore Catalyst utilizes a tri-core design and advanced precious metal coating process to ensure optimal flow while satisfying ECU emissions readiness. Developed through molecular bonding technology, the wash process guarantees long-lasting performance and allows you to push your build further—without the hassle of a CEL.
Get More Out of Your Cat-Back
If you're already running an IE catback system, adding the ProCore Downpipe unlocks its full potential. The factory downpipe acts as a major restriction, especially when tuning or upgrading turbos. The IE downpipe transforms your catback into a true turbo-back exhaust, unleashing deeper sound and maximum flow.
Built for High Output
The full 3" mandrel-bent piping, combined with the 5" 200CPSI catalyst, is designed to handle the power demands of tuned engines and hybrid turbos. It maintains a balance between high exhaust velocity and emissions compliance, giving you the performance edge without compromise.
Precision Fitment, Built to Last
Utilizing 3D scanning and digital modeling, IE ensures every bend and connection of the ProCore Downpipe perfectly fits your MK8 Golf R or 8Y S3. With hand TIG welding, smooth internal transitions, and OE-style mounting, installation is seamless, and durability is unmatched.
Straightforward Installation
