Unlock an improved exhaust note and increased flow for the Audi S4 and S5 3.0T without triggering a check engine light!
Integrated Engineering ProCore Downpipes for B9/B9.5 3.0T engines feature an all-new, in-house-engineered, 6" 400CPSI catalytic converter with a specialized tri-core catalyst and precious metal coatings. This design passes all vehicle readiness monitors while providing substantial flow gains over stock to support ECU tunes and hybrid turbochargers.
Thanks to the Integrated Engineering ProCore Downpipes, B9 owners can now enjoy a free-flowing exhaust with CEL-free operation.
THE PROCORE ADVANTAGE
Integrated Engineering's in-house engineered ProCore Catalyst features their own tri-core design with a specialized coating, enabling it to pass vehicle readiness monitors without triggering a check engine light. An advanced molecular bonded wash process applies the precious metal coatings to ensure long-life reliability. Whether you're looking to improve the exhaust note from your 3.0T or building a track-destroying hybrid turbo setup, enjoy your exhaust without the annoying check engine light.
HIGH-FLOW DESIGN
No check engine light does not equal reduced power. The 6" 400CPSI CAT maintains optimal flow to support substantial power gains up to large and hybrid turbochargers. Your IE ProCore downpipe will pass vehicle readiness monitors and allow total and complete power, torque, and spool potential from your hardware and tuning upgrade investments.
ADVANCED ENGINEERING
Advanced 3D scanning tools and cutting-edge software provide our engineers with a high-resolution digital model of Audi's unique 3.0T engine. This data is then used to maximize the downpipe size for flow and ensure perfect and factory-like fitment.
CUTTING-EDGE MANUFACTURING
IE downpipes are manufactured with quality materials for lasting strength and performance. The T304L stainless steel investment cast body smoothly transitions exhaust flow from the massive 6" CAT to the dual 2.5" mandrel bent exhaust legs. All joints are hand TIG welded using precise fixtures and tooling for a seamless, leak-free fit.
HYBRID TURBO READY
The stock downpipe becomes a significant restriction when upgrading to a larger hybrid turbo. IE's cast downpipe is a direct fit to available upgraded turbochargers on the market and will unleash the complete horsepower, torque, and spool potential from your turbocharger investment.
The Integrated Engineering B9 3.0T intake systems, turbo inlet pipe, and downpipe are hybrid optimized, making the installation of popular turbo upgrades an easy bolt-in process.
