Fabspeed Range Rover 5.0-liter Supercharged V8 Primary Sport Cat Downpipes


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.

High performance catted downpipes replace the restrictive OEM factory Range Rover V8 4 catalysts with high flowing HJS German imported HE Euro 6 certified 200-cell catalytic converters for improved performance and gutsy throaty exhaust sound.                                                      

We're proud to have designed and built in-house an effective way to unlock more power and sound from your supercharged 5.0 Liter V8 Range Rover.
