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.
The most aggressive sounding exhaust solution for the Porsche 991 Turbo. Fabspeed's Supersport X-Pipe Exhaust System with choice of tips, Sport Headers, and Cat Bypass Pipes add significant power and a glorious sound
Give your 991 Turbo the sound and power it deserves with Fabspeed's Supersport RACE Performance Package! Replaces the mundane and quiet factory exhaust sound with a throaty and aggressive performance exhaust note, allowing the car's true character to be heard and felt. Fabspeed's Supersport RACE Performance package adds a level of true excitement to the driving experience of the Porsche 991 Turbo by shortening the spool time of the turbos and providing quicker acceleration and improved throttle response.
