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.    If you'd like to learn more, watch our video about HJS catalytic converters.

Fabspeed's GT420 STREET Performance Package is the premium solution to adding performance to your GT4 / Spyder on the street. Delivering over 400 horsepower to the crank with easy-to-install bolt-on upgrades, there is no better option for the GT4 owner seeking maximum power and performance while retaining catalysts. No need to swap engines or suffer long periods of downtime during a full engine re-build. Simply install the Fabspeed GT420 Package and begin outperforming the 911 Carrera GTS the very next day!
