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.
HJS HD 200-CELL CATALYSTS:
HJS 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:
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.
HEAT BLANKETS:
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.
