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

Factory equipment is GARBAGE compared to these! These free up so much more flow in the exhaust system. Sounds amazing even with the factory muffler. Definitely louder, but nothing over-bearing. Can't wait to get her back on the dyno and see what's what! Also love that there is no CEL. The heat blankets are kind of ugly but they serve a purpose so I can live with them. Just a shame to cover up the beautiful piping and welds!
