Unfortunately the AWE Performance Catalyst is not available for purchase in the US at this time. Please contact us with any questions you may have.

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.

Performance Catalyst-specific downpipes:

Given the increase of airflow with the Performance Catalyst, special resonators were developed to keep frequencies in check, and drone defeated. Though they are not required to run the Performance Catalyst, we strongly recommend and encourage the use of these specific downpipes when equipping the Performance Catalyst for a drone-free experience.
