Welcome! HJS North America, LLC, located in the U.S., is a Factory Authorized Dealer for HJS Emission Technology GmbH & Co. KG, Germany. HJS is the leading factory for Motorsport and Tuning Catalysts in Europe. We specialize in HJS Hi-Flow 200 C.P.S.I. (Cells Per Square Inch) Universal Tuning Catalytic Converters (9095 0092, 9095 0080and9095 0182) for your BMW, Porsche, Mercedes-Benz, Ferrari, Lamborghini, Aston Martin, Audi, VW, Honda, Acura, Toyota, Lexus, Nissan, Infiniti, Mitsubishi, Subaru, Mazda, GM, Ford, Chrysler, etc.
Our model 9095 0092 HJS Hi-Flow Universal Catalyst can handle an engine up to 2.6 Liters and 240 HP, while two can handle an engine up to 5.2 Liters and 480HP.
Our model 9095 0080 HJS High Flow Universal Catalyst can handle an engine up to 3.5 Liters and 280 HP, while two can handle an engine up to 7.0 Liters and 560 HP.
Our model 9095 0182 HJS Hi-Flow Universal HD Catalyst can handle an engine up to 5.0 Liters and 350 HP, while two can handle an engine up to 10.0 Liters and 700 HP.
Any of these HJS Catalysts can be used for 95% of the vehicles on the road since most are under 480 HP, 560 HP, and 700 HP.
All European vehicles 2008 and later must use HJS HD (High Durability) Catalysts which are EURO 5 Compliant. HJS HD Catalysts has a higher durability and a special coating for EURO 5 vehicles. All European vehicles up to 2007 can use regular HJS Catalysts.
Provide power gains up to 30HP, with the addition of performance air filter and cat-back performance exhaust, depending on Catalyst model and Vehicle. Additionally, power gains up to 68BHP have been achieved in the UK with ECU engine reprogramming, depending on the catalyst model and vehicle.
Will give you 90% airflow, compared to a decreased range of 50%-65% or less airflow through your restricted stock catalytic converters and other aftermarket catalytic converters, with 90% airflow being the highest airflow available in a catalyst that is street legal. Our "HJS cats" will also give just enough backpressure to maintain low-end torque.
Will provide a reduction of up to 60% less backpressure, compared to other catalytic converters. No matter what modifications you do to your vehicle, stock catalytic converters will always restrict the air flow and decrease the HP.
Increases MPG, which alone will pay for itself over time.
Have a Unique Construction
Have a 100% Stainless Steel High Quality Metallic Matrix which will withstand extreme temperatures that can damage other metallic and ceramic catalysts.
Have a matrix with a unique S-winding construction, which makes it four times more durable than other metallic catalysts. This construction also prevents breakdown and telescoping, which other catalytic converters are prone to.
Are made from 100% Stainless Steel.
Are 100% manufactured in Germany.
Can handle temperatures up to 1050 degrees Celsius compared to 800 degrees Celsius for most other catalysts and therefore, are able to withstand high (EGT) Exhaust Gas Temperatures.
Have a higher content of precious metals compared to other tuning or aftermarket catalysts which allows the reactions to catalyze from carbon monoxide to carbon dioxide, from nitrogen oxides to nitrogen and oxygen and from unburnt hydrocarbons to carbon dioxide and water, all so they can be safely released into the environment, thereby reducing air pollution and being environmentally friendly.
Provide the Best Value for your Vehicle
Are Universal, so they can be welded into almost any vehicle, as long as the engine size and HP falls within the ratings. HJS High Flow Universal Tuning Catalyst 9095 0092 can be fitted into almost all BMW 3 series, 5 series, 7 series, Z series and M series. Others may require the HJS High Flow Universal Tuning Catalyst 9095 0080 for increased engine size or HP. Some vehicles may require two catalytic converters; using two of the HJS High Flow Catalyst 9095 0092 will give a total rating of 5.2 Liters and 480 HP and using two of HJS High Flow Catalyst 9095 0080 will give a total rating of 7.0 Liters and 560 HP.
OBD II, MOT, Euro 3, Euro 4, Euro 5 Compliant.
Will pass U.S. emissions and inspections tests in 49 states except California.
2 Yrs / 50,000 Miles Manufacturer’s Warranty.
Will give you the highest airflow and strictest emissions, without sacrificing power and sound.
Will give you affordable pricing for superior performance.
* Please note - We can only sell to California residents for off road/racing vehicles, which may not be used on a highway.
