Fabspeed Sport Catalytic Downpipes (992 Turbo)


Designed to Fit:

  • 2021+ Porsche 911 Turbo / Turbo S (992)

Product Details

The Fabspeed Sport Cats utilize German HJS 200 cell HD high-flow trimetallic catalytic converters for maximum exhaust gas flow and performance with zero check engine light worries. Compared to the factory 700 cell Ceramic Catalytic converters, these 992 Turbo S downpipes provide a great performance and sound upgrade.

HJS German imported catalytic converters are made from some of the highest grade material 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 90-95% 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.
