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.
Track Edition Exhaust
For those who like it loud, go Track.
The Track Edition Exhaust is equipped with the same precision-engineering as its Touring Edition counterpart, minus the resonators up front and 180 Technology® resonators in the rear. Instead, the Track Edition comes complete with non-resonated downpipes and straight pipe sections -- leaving the integrated x-pipe as the only filter.
This version is known to get rowdy, and may be too much for many. For that reason, this particular version cannot be returned due to sound preference. Prepare yourself.
