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.Â
Take your 570S to a completely new level of power and excitement with approximately 700 horsepower on tap by upgrading the exhaust, catalytic converters, and ECU tuning parameters. Includes Fabspeed's exclusive Bolt-On Tips for more aggressive styling.                    Â
TRIM LEVELS
The Street Performance Package comes with the following products:
 McLaren 570S / 570GT / 540C Sport Catalytic Converters
Supersport X-Pipe improves power and throttle response while reducing weight by 8lbs and adding true hypercar-worthy exhaust sound
Factory Exhaust: 22lbs / 10kg
Fabspeed X-Pipe: 14lbs / 6.4kg
Fabspeed's Catbypass Pipes replace the restrictive factory catalytic converters with much less restrictive straight-through pipes for maximum flow and performance. Less restriction after the turbo allows for faster spooling, boost response, and a crisp sports car sound with maximum turbo noise.
Fabspeed's optional Sport Cats are constructed with Fabspeed-proprietary HJS German-imported high-flowing catalytic converters using T304L stainless steel. These cats have been designed by HJS and specifically optimized for the McLaren for maximum performance with NO check engine light, guaranteed
All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty

ABOUT
Fabspeed is an industry leader in designing and fabricating performance parts for McLarens. We were the first to manufacture exhaust components for the MP4-12C in 2012, going as far as to source custom 300 cell HJS HD catalysts through our exclusive relationship with HJS. We invested in our own MP4-12C to use as a continued development platform and have refined our exhaust components and utilized our in-house tuner to extract maximum power with ECU tunes. Once we got our hands on a 570S for development, we dedicated ourselves to producing a suite of performance parts to take it to the next level. You can read all about our development process here.
