Description

The Integrated Engineering IEEXCZ2 ProCore Downpipe is engineered to enhance the performance and sound of your Audi B9 SQ5. Designed with a focus on high flow, this downpipe supports upgraded hybrid and large turbochargers, unlocking greater power potential. It features IE's specialized ProCore Catalyst with a tri-core design and advanced coating, ensuring it meets vehicle readiness monitors without illuminating the check engine light. The downpipe is crafted from T304L stainless steel with investment casting and hand TIG welded joints for superior strength and a leak-free fit. This component boasts a high-flow, 6-inch, 400 CPSI catalytic converter that maintains optimal exhaust flow, crucial for maximizing gains from turbocharger upgrades. Real-world dyno testing on a hybrid turbo-equipped B9 S4 confirmed significant power gains of 45 HP and 41 ft-lbs to the wheels. The factory heat shield and engine cover can be reinstalled for a stealth appearance, with an estimated installation time of 2-3 hours. The product's advanced 3D scanning and software engineering ensure a perfect, factory-like fitment. This downpipe is compatible with the Audi SQ5 B9 (2018-2024) 3.0T engine.
