Introducing the IE ProCore Downpipe, a transformative enhancement for Audi B9 S4 or S5 vehicles designed to optimize exhaust notes and amplify flow efficiency. Crafted in-house, the proprietary 6" 400CPSI catalytic converter demonstrates meticulous engineering, ensuring exceptional flow capacity to accommodate advanced engine tuning and larger turbochargers. The distinct tri-core design, augmented with precious metal coatings, seamlessly aligns with ECU emissions criteria, enabling upgrades without triggering the notorious check engine light.

The ProCore Advantage offered by IE is a testament to their pioneering engineering. Boasting an exclusive ProCore Catalyst with a specialized tri-core pattern and coating guarantees compliance with vehicle readiness monitors while avoiding any check engine light issues. The revolutionary molecular bonding process applies precious metal coatings, underscoring the component's durability. Whether the aim is to enrich the 3.0T exhaust note or to construct a potent hybrid turbo setup, drivers can relish an upgraded exhaust experience without the inconvenience of check engine light disturbances.

The High-Flow Design ensures heightened flow dynamics. Dispel any notions of compromised power – the 6" 400CPSI CAT keeps flow unhindered, bolstering significant power gains, particularly when paired with large and hybrid turbochargers. The IE ProCore downpipe takes on the role of a readiness monitor-passing conduit, enabling the extraction of total power, torque, and spool potential from hardware and tuning investments.

Advanced Engineering takes center stage. Leverage cutting-edge 3D scanning tools and sophisticated software, empowering IE's engineers to create a high-resolution digital blueprint of Audi's distinctive 3.0T engine. This blueprint is the foundation for optimizing downpipe dimensions, ensuring unmatched flow and fit to factory specifications.

Enter the realm of Manufacturing Excellence. IE downpipes are crafted from premium materials to ensure resilience and lasting performance. The T304L stainless steel investment cast body guarantees a seamless exhaust flow transition from the expansive 6" CAT to the dual 2.5" mandrel bent exhaust legs. Each joint is meticulously hand-tIG welded, utilizing precision fixtures and tools, resulting in an impeccable, leak-free fit.

Anticipate Hybrid Turbo Readiness. The stock downpipe becomes a bottleneck when transitioning to larger hybrid turbos. IE's cast downpipe, a plug-and-play marvel, seamlessly integrates with a range of upgraded turbochargers available on the market. Unleash your turbocharger investment's complete horsepower, torque, and spool potential.

The IE ProCore Downpipe redefines driving encounters, where innovation, performance, and ingenuity unite to revolutionize exhaust enhancement.
