In comparison to commercially available linear frustums, the \"eddy catalytic technology\" adopts an arc-packaging method. The turbine emissions process produces a vortex effect which purifies the exhaust gases while maintaining an equal amount of back pressure. When compared to a variety of conventional straight downpipes, the patented eddy catalytic technology can effectively increase horsepower and torque. In the lower rpm you will be immerse with vast amount of torque until you reach higher rpm where the vortex effect really comes to life and opens up the Catalytic, resulting in a performance similar to a 100 CELL Catalytic. However in the lower rpm, the catalytic will produce efficient and clean emission similar to a 400CEL Catalytic and produce no Check Engine Lights, completely error free.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003ePatented O2 sensor technology design provides real-time data performance by accurately sensing every rotating displacement.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eNo more delayed in power delivery\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eUsing one of the rare noble metal to help efficiently filter out exhaust gas.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eComputer simulation to obtain the best diameter\u003c\/span\u003e\u003cspan\u003e.\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSpecial 3D design to achieve 100% OEM fitment, no modification required.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSUS304 Premium Grade Stainless steel.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eDual Cross-Welding Technology providing substantial increase durability at the t\u003c\/span\u003e\u003cspan\u003eurbo Flange.\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eUK MOT friendly and Euro 6 Compliant\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003carticle class=\"unreset\" data-scroll-scope=\"\"\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/article\u003e\n\u003cp class=\"unreset\"\u003e\u003cstrong\u003ePower Gain\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePOWER \u003cspan\u003e+7.1 PS \u003c\/span\u003eat 5\u003cspan class=\"num2\"\u003e988\u003c\/span\u003erpm\u003c\/li\u003e\n\u003cli\u003eTORQUE \u003cspan\u003e+20.60nm \/ 15.19ft-lb of torque \u003c\/span\u003eat 4461rpm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp class=\"unreset\"\u003e\u003cspan\u003e\u003cstrong\u003eR\u0026amp;D and 3D Scanning\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"unreset\"\u003e\u003cspan\u003eStone Exhaust engineers use reverse engineering by 3D scanning OEM parts to understand their functionality and identify weaknesses.
