McLaren is constantly updating their vehicles and offering even better performance, and we're dedicated to doing the same. Fabspeed is the global authority for aftermarket McLaren performance.
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.
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!
