At 3 inches in and out with a 7 inch body, the GE-90147 is shorter and easier to package than traditional high flow cats, making it a practical choice for builders working with limited routing space in engine bays, X pipes, or mid pipe configurations. The T304 stainless steel body is built to handle the thermal cycling demands of a performance exhaust system.\u003c\/p\u003e\n\n\u003cp\u003eThe GreenCats substrate inside this converter is formulated to flow at levels appropriate for modified engines while still meeting EPA standards for 49 state street certification. Platinum coated construction ensures fast catalyst light off even at lower exhaust temperatures, and furnace brazed end caps keep the converter sealed under pressure. Kooks builds this converter to the same quality standards as the GreenCats units bundled with their vehicle specific header kits, so you get the same technology in a standalone form for custom fabrication work or direct replacement duty.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUniversal 3 inch inlet and outlet for 3 inch exhaust system compatibility\u003c\/li\u003e\n  \u003cli\u003eCompact 7 inch body length for tight routing situations\u003c\/li\u003e\n  \u003cli\u003eEPA certified for 49 state street use\u003c\/li\u003e\n  \u003cli\u003eHigh output GreenCats substrate for performance flow\u003c\/li\u003e\n  \u003cli\u003eT304 stainless steel body\u003c\/li\u003e\n  \u003cli\u003ePlatinum coated substrate for rapid catalyst activation\u003c\/li\u003e\n  \u003cli\u003eFurnace brazed end caps for a sealed, durable assembly\u003c\/li\u003e\n  \u003cli\u003eNot CARB certified; not for sale or installation in California\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eWhat's Included\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x universal 3 inch GreenCats catalytic converter with 7 inch body\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003eDetail\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePart Number (MPN)\u003c\/td\u003e\n\u003ctd\u003eGE-90147\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003eContact us for UPC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInlet Diameter\u003c\/td\u003e\n\u003ctd\u003e3 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutlet Diameter\u003c\/td\u003e\n\u003ctd\u003e3 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBody Length\u003c\/td\u003e\n\u003ctd\u003e7 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBody Material\u003c\/td\u003e\n\u003ctd\u003eT304 Stainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSubstrate\u003c\/td\u003e\n\u003ctd\u003ePlatinum Coated High Output GreenCats\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eEPA Certified\u003c\/td\u003e\n\u003ctd\u003eYes, 49 state (not CARB)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCalifornia Legal\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eConnection Type\u003c\/td\u003e\n\u003ctd\u003eUniversal Weld In\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFitment\u003c\/td\u003e\n\u003ctd\u003eUniversal\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch4\u003eFrequently Asked Questions\u003c\/h4\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat size exhaust pipe does this converter fit?\u003c\/strong\u003e\u003cbr\u003e\nThis converter has a 3 inch inlet and 3 inch outlet, designed for installation into 3 inch exhaust tubing via weld on connections.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs this converter EPA certified?\u003c\/strong\u003e\u003cbr\u003e\nYes.
