Description
Unleash the full performance potential and sound of your VW MK8 GTI with the Integrated Engineering (IE) ProCore Downpipe, engineered for maximum power gains, rich exhaust tone, and emissions compliance—without the hassle of a check engine light.
At the core of this system lies IE’s proprietary 5" 200 CPSI ProCore catalytic converter, designed with a unique tri-core matrix and a high-density precious metal coating. This advanced engineering balances ultra-high exhaust flow with clean emissions to pass readiness monitors and remain CEL-free, even on modified vehicles.
Key Features:
-
ProCore Catalyst Technology – Specialized tri-core design with rare-metal coatings eliminates check engine lights.
-
Increased Exhaust Volume – Delivers a deep, full-bodied exhaust tone for an enhanced driving experience.
-
Supports Big Power Builds – Built to handle Stage 2 tuning, hybrid, and larger turbocharger setups.
-
Direct Bolt-On Fitment – No cutting, welding, or custom fabrication required.
-
Premium Materials & Build – Constructed from T304L stainless steel, TIG welded, and investment cast for smooth transitions and unmatched durability.
-
OEM-Style Flex Section – Absorbs engine movement and maximizes longevity.
ProCore Advantage – No CEL, No Compromises
Unlike traditional high-flow catalytic converters that may sacrifice emissions compliance or trigger fault codes, IE’s ProCore Catalyst uses a tri-core design and precision-applied metal wash coating to clean exhaust gasses while maintaining full power potential. This means you can push performance to the limit while staying within ECU parameters and avoiding check engine lights.
Big Sound, Bigger Flow
Want more sound? Pairing this downpipe with an IE cat-back exhaust system transforms your MK8 GTI into a true turbo-back setup—unlocking an aggressive and exhilarating exhaust note that reflects the power under your hood.
Dyno-Proven Design
IE uses advanced 3D scanning tools and CAD modeling to optimize downpipe geometry for performance and perfect fitment. Combined with a 3” mandrel-bent design and smooth transitions, this downpipe eliminates exhaust restrictions and promotes faster turbo spool, increased torque, and greater horsepower across the powerband.
Installation Made Simple
The IE ProCore Downpipe is designed for hassle-free installation with no permanent modifications. All necessary hardware is included for a smooth, bolt-on process.
-
Installation Time: Approximately 2–3 hours with standard tools
-
Emissions Readiness: Designed to pass readiness monitors without triggering a CEL (Check Engine Light)
