Fabspeed McLaren MP4-12C HJS Sport Cats

Fabspeed McLaren MP4-12C HJS Sport Cats: HJS sport catalytic converters, for the 2012-2014 McLaren MP4-12C.

Sound

In Fabspeed's words: "The best way to improve sound on your MP4-12C is replacing the factory catalytic converters with high flow units. Expect to hear more turbo spool, more higher frequencies, and ultimately a much more raw exhaust note that will let the McLaren V8 sing."

Design

These sport cats use HJS HD high-flow catalytic converters to improve power and throttle response and add a true hypercar sound. Less restriction after the turbos means faster spooling and boost response. Fabspeed guarantees no catalyst-generated check engine light.

Build

Fabspeed reports gains of 28 whp and 29 lb-ft, and a 5 lb (2.2 kg) saving. 200-cell HJS HD converters in T304L stainless steel with investment-cast inlets and outlets. Heat blankets are T312L mesh, Kevlar and ceramic insulation.

Use

Fabspeed sells these high-flow sport catalytic converters for off-road and competition use only. Check your state and local emissions rules before you buy.

Install

Fabspeed designs it to bolt on in place of the factory parts, with no cutting or welding.
