Porsche Sport Cat with Downpipe For Porsche 718 Boxster (2017-2025), 718 Cayman (2017-2025) Models.

Unlock Enhanced Sound, Power, and Throttle Response

The Fabspeed Sport Cat with Downpipe is a premium bolt-on upgrade designed to significantly enhance the performance and auditory experience of your Porsche 718 . Featuring high-quality, German-made HJS 200-cell EURO 6 EC certified compliant trimetallic catalytic converters, this system ensures optimal flow and emissions compliance without triggering a check engine light.

Constructed from durable, mandrel-bent T304L stainless steel, the 3-inch tubing smoothly transitions to dual 2-inch outlets from the catalytic converter to integrate seamlessly with the rest of your exhaust system. We’ve utilized the largest and highest-flowing catalytic converters that can be accommodated in the 718 chassis. Larger catalytic converters offer the dual benefit of increased exhaust flow and a greater catalyst surface area, resulting in more effective exhaust gas filtration for emissions compliance. This Sport Cat with Downpipe is engineered as a direct bolt-on replacement for the factory 718 catalytic converter and downpipe.

SOUND:

Experience a richer and more pronounced boxer engine rumble with the installation of our Sport Cat with Downpipe. Designed to eliminate unwanted droning, this upgrade intensifies the characteristic flat-four sound. Engaging Sport mode will further amplify the exciting cracks and pops during gear changes and deceleration. You can also expect a subtle increase in turbocharger noise, which can be further enhanced at any time by adding our complementary Maxflo Exhaust System.

POWER:

Fabspeed’s Sport Cat with Downpipe is estimated to deliver a noticeable gain of 20 wheel horsepower (whp). For even greater power gains, we recommend pairing this hardware upgrade with a custom Fabspeed ECU Tune, which can further optimize the engine’s performance to take full advantage of the increased exhaust flow.

FINISH:

Crafted from high-quality T304L stainless steel, each Sport Cat with Downpipe is meticulously TIG welded by our expert craftsmen. You have the choice of finishing your system with either our hand-made single-wall stainless steel tips or our premium matte carbon fiber shrouded tips, allowing you to tailor the look to your preference.
