Fabspeed McLaren 675LT Sport Cats



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.

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

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.

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.

All Fabspeed performance products are backed by the Fabspeed Lifetime Limited Warranty
