Over time, the internal OEM ceramic washcoat suffers from thermal degradation, substrate fracture, and sintering. This leads to exhaust flow restriction, increased pre-turbine backpressure, sluggish boost spool, and continuous catalytic efficiency DTCs (P0420\/P0430) on your \u003cstrong\u003eAlpha\u003c\/strong\u003e chassis vehicle.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eManufactured as a bolt-in replacement, this front catalytic assembly is engineered with a high-flow ceramic substrate formulated with a durable precious-metal washcoat to efficiently oxidize carbon monoxide and unburnt hydrocarbons. Fabricated with heavy-duty stainless steel piping and thick-gauge flanges, it incorporates a precision-welded 2-bolt inlet and a 4-bolt outlet designed to mate flush against the stock turbine housing and mid-pipe. Pre-welded, factory-located O2 sensor bungs allow direct reinstallation of your upstream and downstream lambda sensors without harness alteration.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 × Front Catalytic Converter\u003c\/li\u003e\n  \u003cli\u003eInstallation Accessories\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2013-2019 Cadillac ATS\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003eLTG\u003c\/strong\u003e 2.0L Turbo \/ \u003cstrong\u003eAlpha\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e272 hp \/ 295 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003e12670571\u003c\/strong\u003e, \u003cstrong\u003e12673998\u003c\/strong\u003e, \u003cstrong\u003e12679573\u003c\/strong\u003e, \u003cstrong\u003e19420226\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2013-2019 Cadillac ATS 2.0L Turbo (Front Position)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the Alpha chassis ATS?\u003c\/h4\u003e\n\u003cp\u003eYes, this unit is a direct fit for 2013-2019 Cadillac ATS models equipped with the 2.0L Turbo \u003cstrong\u003eLTG\u003c\/strong\u003e engine. \u003cstrong\u003eThis converter does not fit V6 3.6L models, ATS-V 3.6L Twin-Turbo models, or naturally aspirated 2.5L configurations.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eIs this catalytic converter legal for road use in California or CARB states?\u003c\/h4\u003e\n\u003cp\u003eNo, this unit is an EPA-compliant 46-state legal converter and is restricted from shipping to, sale in, or registration within California, New York, Colorado, and Maine.\u003c\/p\u003e\n\n\u003ch3\u003eThe Cadillac Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to preserve the refined acoustic dampening and high-output response expected from Cadillac's rear-wheel-drive sport architecture, this emissions solution maintains exact exhaust velocities to keep boost delivery responsive and avoid false diagnostic trouble codes.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67916924354808,"sku":"DS-EMMOSAXNA","price":199.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-cadillac-ats-2013-2019-2-0l-front-1.jpg?v=1793478643","url":"https:\/\/performancechiptuning.com\/products\/catalytic-converter-for-cadillac-ats-2013-2019-2-0l-front","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
