The company employs flow velocity measurement software in 3D and the technique of one-piece bend pipes, along with mechanical arms which accurately welds without generating ash in the pipe wall in order to further exhaust efficiency of De-Cat downpipes. It is a perfect and effective product which has surpassed all similar products in the market.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003cbr\u003e\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eCatless downpipe for 535i, 640i, X5 xDrive 35i, X6 xDrive 35i with N55 engine.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003eUnique Flex design to prevent breakage caused by extreme heat \u003c\/li\u003e\n\u003cli\u003eCrisscross welding to strengthen turbo flange\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eOne Piece Design\u003c\/li\u003e\n\u003cli\u003eMachine Welding\u003c\/li\u003e\n\u003cli\u003eIn House Research and Development\u003c\/li\u003e\n\u003cli\u003e3D Scanning \u0026amp; Reverse Engineering\u003c\/li\u003e\n\u003cli\u003e100% OEM Fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eR\u0026amp;D and 3D Scanning\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eStone Exhaust engineers use reverse engineering by 3D scanning OEM parts to understand their functionality and identify weaknesses.
