FabSpeed Porsche 991.2 GT3 / GT3 RS Performance Package (2017+)

Why We Choose HJS Catalytic Converters:  HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light.     Fabspeed unique high-performance exhaust solution for the Porsche 991.2 GT3 / GT3 RS; fantastically daily-driveable sound and power from Fabspeed's Sport Performance Headers, Valved Side Muffler Bypass Pipes, Deluxe Dual Style Tips and Fabspeed ECU Tune Upgrade.
