Fabspeed McLaren MP4-12C Sport Cats



Replaces the four restrictive factory catalytic converters with two ultra high-performance HJS German Racing sport cats for maximum performance and sound

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 is the authority for aftermarket McLaren performance.

Our competitors solution to utilizing larger catalysts necessitates a harsh outlet angle, resulting in exhausts gasses exiting in an efficient manner. Fabspeed invested in cast inlets and outlets for the smoothest possible flow both in and out for maximum exhaust velocity and power.

Keeping 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.

Fits all McLaren MP4-12C vehicles (2011-2014)

Improves power by 28whp and 29 ft-lbs of torque to the wheels

Less restriction after the turbo allows for faster spooling and boost response

NOTE: Fabspeed’s 200-cell high-flow catalytic converters are not C.A.R.B. certified and are for Off-Road Use ONLY in the state of California

All Fabspeed performance products are backed by the Fabspeed Lifetime Limited Warranty
