FABSPEED MOTORSPORT | McLaren 650S Performance Package Demo (01:18)
Fabspeed is proud to release our new Performance Package exhaust system for the McLaren 650S, including proprietary high-flow 300-cell HJS Sport Catalytic Converters and a high-performance X-Pipe rear exhaust section. (Also available without catalytic converters for additional power and volume!)

Product Description

Replaces the restrictive factory catalytic converters with much less restrictive straight-through pipes for maximum flow and performance                                                             

Our included heat blankets consist of a 13mm thick ceramic fiber refractory matt 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.

 

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.

 

HEAT 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!

 

FEATURES:

  • Fits all McLaren 650S vehicles
  • Increases horsepower and torque by 33 whp and 24 ft-lbs
  • Saves 10 lbs from the vehicle versus bulky factory catalytic converters
  • Fabspeed's Primary Catbypass Pipes replace the restrictive factory catalytic converters with much less restrictive straight-through pipes for maximum flow and performance.
  • Direct bolt-on replacement for the heavy factory catalytic converters
  • Adds an aggressive exhaust note for exotic high-performance sound
  • Constructed from high-quality 14-16 gauge C.N.C. mandrel-bent T304L stainless steel for optimum flow and maximum durability 
  • Optional 02 spacers available to help prevent triggering the Check Engine Light
  • All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty
