Why We Choose HJS Catalytic Converters:
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 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.

Fabspeed Motorsport is proud to offer a complete high-performance exhaust and tuning solution for the 2017+ McLaren 720S. We've had ample time with numerous vehicles in house to develop the very best exhaust system and an ECU Tune to extract maximum power out of our hardware. Drivability is greatly increased with significant power gains throughout the power band and the sound is utter perfection. The system offers a pleasing upgrade in tone from the factory system. With Cat Bypass Pipes you can expect a race car roar with loud backfires when you let off the throttle. Let the full fury of the 720S shine as all heads turn around you or go with the Sport Catalytic Converters for an aggressive but more subtle sound. Enjoy the ultimate power and sound solution for your McLaren.
