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 horsepower tests and straight downpipes, our patented eddy catalytic technology can effectively increase horsepower and torque.\u003cbr\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\u003eNo error code nor check engine light\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\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.
