Replaces the restrictive factory catalytic converters with two ultra high-performance HJS German-imported Sport Cats for improved performance and hypercar sound. Clean and Green Performance from Fabspeed Motorsport USA.

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 an investment cast inlet pipe 4.5″ diameter 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 Wolrds 1st and Best authority on Mclaren Performance as we have the most experience. Do not waste your time with cheap copy cats and Chinese Taiwanese rebranded re-boxed systems.HJS German Imported HD 200-CELL CATALYSTS- Flows 90% of a straight pipeHJS manufactures the highest quality catalysts in the world. Fabspeed has incorporated 200 cell-HJS HD catalysts into our latest design to maximize horsepower.

CAST INLETS AND OUTLETS

Our competitors solution to utilizing larger catalysts necessitates a harsh outlet angle, resulting in exhausts gasses exiting in an inefficient manner. Fabspeed invested in CAD designed investment cast inlets and outlets pipes for the smoothest possible flow both in and out for maximum exhaust velocity and power. 4.5″ diameter bigger than any competitors systems for maximum power and turbo boost transition.

HEAT BLANKETS

Keeping heat in the exhaust maintains the maximum velocity of exhaust gasses, allowing the turbos to spool faster while ensuring maximum power is extracted through increased thermodynamic efficiency and flow. Fabspeed thermal blankets are rated to 1800 degrees. T321L Stainless steel mesh over a 321L stainless steel inner 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. Ultimate thermal heat solution way better and more expensive than re-using Mclaren heat shields and or any thermal coatings which are a JOKE. Fabspeed thermal blankets are exclusively manufactured by a military defense contractor for aviation and marine critical systems!

FEATURES

• Fits all McLaren 570S / 570GT / 540C vehicles worldwide
• System comes with thermal 1800 degree rated military specification blankets included
• Improves power and throttle response while adding true hypercar-worthy exhaust sound

• Optimized for maximum performance with NO catalyst generated check engine light, guaranteed
• CAVEAT EMPTOR- only HJS German EMITEC catalytic converters should be installed on any Mclaren. EMITEC/HJS came factory equipped when new — dont go with substitute no-name Mongrel Chinese Taiwanese bullshit cats or catbypass pipes.

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.

FABSPEED MOTORSPORT USA was appointed 20 years ago as HJS Emissions Technology Menden Germany as HJS Exclusive importer and distributor for all of North and South America. Therefore when you purchase HJS catalytic converters and or Fabspeed systems equipped with HJS catalytic converters the PURCHASER is 100% ASSURED that they have received Genuine certified high-performance HJS components imported directly from HJS Emitec Germany.

ONLY Fabspeed Motorsport can offer HJS German direct imported catalytic converters in the USA. Any other company offering HJS Equipped products SHOULD be QUESTIONED before purchase as to where they obtained HJS Catalytic converters.
