AWE Tuning Performance Catalyst - Audi S4 / S5 (B9) 3.0T
A precision CNC-machined billet T304 stainless steel flange, massive 145mm 200CPSI EURO 6 HJS catalyst with tri-lobe core, and 2.5” T304L stainless steel make up the Performance Catalyst’s construction for high-flow decongestion and an additional 12 hp and 15 ft-lbs of torque to the wheels.
Exhaust configurations recommended for use with Performance Catalyst:
Given the increase of airflow with the Performance Catalyst, special resonators were developed to keep sound frequencies in check. These larger resonators are included in exhaust configurations labeled as "Resonated for Performance Catalyst," and available independently (to be added to existing AWE exhausts) via the "Resonator Conversion Kit."
Please note: exhausts labeled "Resonated for Performance Catalyst " and the Resonator Conversion Kit are recommended to be used with the Performance Catalyst, but not required. However, Performance Catalysts may not be returned (absent manufacturer defect under normal warranty guidelines) if being run without the recommended exhaust configurations.
