  • Replaces the four restrictive factory catalytic converters with two ultra high-performance 200 cell HJS HD German-imported Sport Cats for improved performance and hypercar sound
  • Constructed from TIG-welded high-quality T304L stainless steel with premium 321 stainless steel flex-sections and smooth cast sections for improved fit and ease-of-installation. Fabspeed is dedicated to offering the best performing downpipes for McLarens and has invested in bespoke components to increase power.
  • Visual comparison between the factory catalytic converters and our high performance Sport Catalytic Converters.
  • Fabspeed's Sport Cats for the McLaren MP4-12C improve power by +28 whp and 29 ft-lbs of torque to the wheels.
  • Fabspeed is dedicated to McLaren performance and through our two development vehicles (MP4-12C and 570S) we've crafted the highest performance Sport Cat Downpipe possible. We now use the highest quality 200 cell HD cat core from HJS Racing in Germany. We’ve incorporated a cast outlet pipe which allows for the smoothest possible flow, the most possible power especially when paired with a tune, and ultimately a superior solution.
  • Keeping the heat in the exhaust maintains the velocity of exhaust gasses, allowing the turbos to spool faster while ensuring maximum power is extracted through increased efficiency. Our included heat blankets consist of a 13mm thick ceramic fiber refractory mat interior rated to 1800 degrees. Stainless steel mesh over liner covering ceramic insulation makes direct contact with the downpipes. The basalt fabric exterior covers sewn with stainless steel mesh covering all edges and high quality stainless steel spring fasteners ensure longevity.
  • Every set of Sport Catalytic Converters is hand made in house at Fabspeed Motorsport.

Product Description

Fabspeed Motorsport USA was the world's very first company to design, engineer, and dyno develop McLaren systems. Fabspeed Motorsport is the company with the most experience with these cars. 

Replaces the four restrictive factory OEM catalytic converters with two ultra high-performance HJS German Racing 200-cell sport cats for maximum performance and sound, and no check engine light guaranteed.                            

Utilizing our two development McLarens, MP4-12C and 570S, we’ve experimented with many designs and were able (after much testing and engineering) to craft the highest quality catted downpipes on the market. We are utilizing bullet proof, high flow 200-cell HJS HD catalysts and incorporate a cast outlet pipe which allows for the smoothest possible flow, the most possible power especially when paired with a tune, and ultimately a superior solution. It’s a major change, but we’ve invested a lot of time and resources into developing the best possible McLaren downpipes and we’re now proud to offer you this latest and greatest solution. McLaren is constantly updating their vehicles and offering even better performance, and we're dedicated to doing the same. Fabspeed Motorsport is the world's primary authority for aftermarket McLaren performance.

HJS HD 200-CELL CATALYSTS:
 
HJS Germany manufactures the highest quality catalysts in the world. Fabspeed has incorporated 200 cell-HJS HD catalysts into our latest design to maximize horsepower. Our complete redesign incorporates these high flowing catalysts in conjunction with heat blankets and makes incredible power gains especially when paired with a complete Fabspeed exhaust and ECU Tune package.
 

CAST INLETS AND OUTLETS:

Investment cast lost wax CAD designed. Fabspeed Motorsport invested in CAD designed cast inlets and outlets for the smoothest possible flow both in and out for maximum exhaust velocity and power. No other company in the world offers this level of dedicated quality. 

 

HEAT BLANKETS:

Included only at Fabspeed Motorsport. Protect your engine components from intense heat with thermal blankets. Keeping heat in the exhaust maintains the maximum velocity of exhaust gasses, allowing the turbos to spool faster while ensuring maximum power is extracted through increased thermodynamic efficiency and flow. Fabspeed thermal blankets are rated to 1800 degrees. T321L Stainless steel mesh over a 321L stainless steel inner liner covering ceramic insulation makes direct contact with the downpipes. The basalt fabric exterior covers sewn with stainless steel mesh covering all edges and high quality stainless steel spring fasteners ensure longevity. Fabspeed thermal blankets are exclusively manufactured by a military defense contractor!

 

FEATURES:

  • System comes with thermal military spec blankets included
  • Fits all McLaren MP4-12C vehicles (2011-2014)
  • Improves power by 28whp and 29 ft-lbs of torque to the wheels
  • Constructed with Fabspeed Motorsport-proprietary 200-cell HJS HD German imported high-flowing catalytic converters using T304L stainless steel
  • HJS catalytic converters flow 93 to 95% of a straight pipe
  • Less restriction after the turbo allows for faster spooling and boost response
  • Optimized for maximum performance with NO check engine light, guaranteed
  • Improved sports car sound and power with less restriction after the turbo for faster spooling
  • All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty
