Replaces the four restrictive factory catalytic converters with straight-through pipes for maximum flow, performance, and sound
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.
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!
- Fits all McLaren 675LT vehicles
Maximizes power and throttle response while adding an aggressive exhaust note
Minimum restriction after the turbo allows for the fastest-possible spooling and boost response
Constructed from high-quality 14-16 gauge C.N.C. mandrel-bent T304L stainless steel for optimum flow and maximum durability
Saves 10 lbs from the vehicle versus bulky factory catalytic converters
Fabspeed's Catbypass Pipes replace the restrictive factory catalytic converters with much less restrictive straight-through pipes for maximum flow and performance.
Optional 02 spacers available to help reduce Check Engine Light occurences
All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty

This is the way the car should have left from the factory in my opinion. Completely free of any and all BS restrictions! Exhaust sounds so much better, and the car pulls so much harder at the top end. Excellent product and great craftsmanship.
