It is intended for owners who already run that X-pipe and want to remove the check engine light without a tune while meeting emissions requirements as specified by the EPA. It fits most aftermarket exhaust systems and mufflers and bolts on with no cutting, welding or modification. Active's proprietary precious metal loading greatly reduces emissions and eliminates most check engine lights, and these high flow converters outperform stock units.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTwo Active AFlow Super High Output flat catalytic converters\u003c\/li\u003e\n\u003cli\u003eUltra high flow 400 cell per square inch catalyst\u003c\/li\u003e\n\u003cli\u003eNo check engine light for catalytic efficiency — no performance tune needed\u003c\/li\u003e\n\u003cli\u003eIncrease of 10+ RWHP with the stock BMW rear exhaust\u003c\/li\u003e\n\u003cli\u003e12+ RWHP measured when combined with the Active Autowerke Signature exhaust system (Active Autowerke Mustang chassis dyno)\u003c\/li\u003e\n\u003cli\u003eRated for 300 to 500 horsepower per cat\u003c\/li\u003e\n\u003cli\u003eWithstands up to 1500 °F\u003c\/li\u003e\n\u003cli\u003eReaches operational efficiency within 9 seconds of start-up\u003c\/li\u003e\n\u003cli\u003eFull 304 stainless steel construction, including the catalyst substrate, furnace-brazed to the mantle\u003c\/li\u003e\n\u003cli\u003eTIG welded 304 stainless steel; cast upper stainless steel V-band for precise fitment\u003c\/li\u003e\n\u003cli\u003eBolts on with factory style flanges — no cutting or welding required\u003c\/li\u003e\n\u003cli\u003eWeighs less than 30 lbs versus the factory system at more than 40 lbs\u003c\/li\u003e\n\u003cli\u003eOne year standard Active Autowerke warranty on exhaust products\u003c\/li\u003e\n\u003cli\u003eCatalytic converters covered by a 5 year \/ 50,000 mile warranty (on shell and tube ends)\u003c\/li\u003e\n\u003cli\u003eMade in Miami, Florida\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTwo Active AFlow super high flow catalytic converters with connecting pipes, as supplied by Active Autowerke; see the installation instructions for the full bill of materials.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003ch3\u003eAdditional Parts Required\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003ca href=\"\/products\/active-autowerke-signature-x-pipe-bmw-e9x-m3\"\u003eActive Autowerke Signature X-Pipe for BMW E9X M3 (11-017)\u003c\/a\u003e\u003c\/strong\u003e — this product is a cats upgrade for the Signature Track Pipe with X-Pipe.
