Less Backpressure, more Power

The diagram shows the result of an exhaust back pressure comparison measurement between a 400 cell original catalyst and a 200 cell HJS tuning catalyst. Test vehicle was a Mitsubishi Lancer Evolution X with a 1998 cm3 turbocharged engine with 295 HP and Euro 4 emission standard. By reducing the number of cells and the catalysts size while optimizing gas flow, a 60% reduction in exhaust back pressure compared to the original part could be achieved. The turbocharger performance could be improved by 8HP and 12Nm torque.
