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 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. 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 YOUR SPORTSCAR MUST  ONLY HAVE  HJS GERMAN AUTOBAHN PROVEN Racing High Flow Catalytic Converters: 

HJS Emission technology German imported EMITEC  catalytic converters are made from the highest grade materials in the WORLD. There is simply no alternative Street, Autobahn and Race Proven catalytic converter that compares in the World. 

HJS German proven catalytic converters offer the Worlds very best high performance power increases along with enhanced Sportscar sound and long term proven durability.  Any and all other brands of catalytic converters simply and quickly degrade , lose power and give the car a Check Engine Light and or do not scrub the exhaust systems as well as the OEM catalytic converters. 

HJS German EMITEC  200CPSI  catalytic converters can flow up to 90-93% of a straight pipe in most applications. The benefit is that you get the "straight pipe exotic sound" while still being able to provide enough emissions scrubbing to prevent a check engine light.   DO NOT ASSUME ALL CATALYTIC CONVERTERS ARE THE SAME or EVIL PErformance killers. HJS EMITEC catalytic converters are 100% Guaranteed to make more power than any Illegal cat-bypass pipes even on Turbocharged engines with aftermarket high performance turbos.  If you'd like to learn more, watch our video about HJS German  catalytic converters.
