  • 2011 - 2014 McLaren MP4-12C

Replace the four restrictive factory OEM catalytic converters with two ultra high-performance German HJS 200-cell sport cats for maximum performance and sound, and no check engine light guaranteed. Utilizing Fabspeed's two development McLarens, MP4-12C and a 570S, they've experimented with many designs and were able (after much testing and engineering) to craft the highest quality catted downpipes on the market. Fabspeed utilizes 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.

The best way to improve sound on your MP4-12C is replacing the factory catalytic converters with high flow units. Expect to hear more turbo spool, more higher frequencies, and ultimately a much more raw exhaust note that will let the McLaren V8 sing. And best of all they won't cause any drone inside the cabin.

Aside form a tune, these are the best bolt on performance adder your McLaren can get! With peak, dyno proven, curve gains of 28 whp and 29ft/lbs of tq, you're going to feel it across in the seat of your pants. 

  • Fits all McLaren MP4-12C vehicles (2011-2014)
  • Improves power by 28 whp and 29 ft-lbs of torque to the wheels
  • Saves 5 lbs/ 2.2 KGs from the rear of the vehicle

  • Heat Blankets are made from T312L mesh , Kevlar, and ceramic insulation for durability and the best insulating performance
  • Investment cast inlets and outlets for best possible flow
  • Less restriction after the turbo allows for faster spooling and boost response
  • Optimized for maximum performance with NO catalyst generated check engine light, guaranteed
  • Improved sports car sound
  • Simple DIY (Do-It-Yourself) bolt-on installation, no cutting or welding required
