  • Fabspeed's Sport Catalytic Converters for the McLaren 675LT provides maximum gains of over 24 whp and 29 ft-lbs of torque at 4350 RPM. Reward yourself with peak power gains of 17whp and 20 ft-lbs of torque, an increase in turbo noise, and an intoxicating cabin presence.
  • Fabspeed is dedicated to McLaren performance and through our two development vehicles (MP4-12C and 570S) we've crafted the highest performance Sport Cat Downpipe possible. We now use the highest quality 200 cell HD cat core from HJS Racing in Germany. We’ve incorporated 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.

Product Details:

Replaces the four restrictive factory catalytic converters with two ultra high-performance HJS German-imported Sport Cats for improved performance and hypercar 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. 

                                                    

FEATURES:

  • Fits all McLaren 675LT vehicles
  • Improves power and throttle response while adding true hypercar-worthy exhaust sound
  • Less restriction after the turbo allows for faster spooling and boost response
  • Constructed with Fabspeed-proprietary HJS German-imported high-flowing catalytic converters using T304L stainless steel.  These cats have been designed by HJS and specifically optimized for the McLaren for maximum performance without excessive triggering of the check engine light.
  • All Fabspeed performance products are backed by the Fabspeed Lifetime Limited Warranty
NOTE: Fabspeed’s high-flow catalytic converters and catbypass pipes are not C.A.R.B. certified and are intended for off-road use only.

  1. What factory? 5 Star Review

    Posted by on 24th Mar 2017

    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!
