Fabspeed McLaren MP4-12C Sport Catalytic Converters - FS.MCL.12C.SC

Replace the four restrictive factory OEM catalytic converters with two ultra high-performance German HJS 200-cell sport cats for maximum performance and sound, and no check engine light guaranteed. Utilizing our two development McLarens, MP4-12C and a 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.

SOUND:

The best way to improve sound on your MP4-12C is replaceing 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. And best of all they won't cause any drone inside the cabin.

POWER:

Aside form a tune, these are the best bolt on performance adder your McLaren can get! With peak, dyno proven, curve gains of 28 whp and 29ft/lbs of tq, you're going to feel it across in the seat of your pants.

Why We Choose HJS Catalytic Converters: 

HJS German imported catalytic converters are made from some of the highest grade material you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light.
