Over extended mileage, the stock internal monolith washcoat sinters and ceramic cells break down or clog. This restriction increases exhaust backpressure against the cylinder heads, spikes combustion chamber temperatures, chokes upper-RPM engine efficiency, and triggers persistent P0420 and P0430 catalyst efficiency trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a bolt-on solution for dual-bank replacement, this left and right direct-fit assembly utilizes a heavy-gauge stainless steel outer shell designed to resist external road corrosion, structural deformation, and weld fatigue. Internally, a high-flow ceramic substrate coated in a uniform precious metal washcoat provides optimal chemical reduction of carbon monoxide, unburnt hydrocarbons, and nitrogen oxides. Robotically aligned, OE-specification connection flanges and pre-welded oxygen sensor bungs guarantee a sealed, leak-free union with the stock exhaust manifolds and intermediate pipes using the supplied hardware.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; margin-bottom: 20px;\"\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;\"\u003e2004-2007 Cadillac SRX\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;\"\u003eLY7 3.6L V6 \/ GM Sigma I\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;\"\u003e255 hp \/ 252 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;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2004 Cadillac SRX Base 3.6L V6 (RWD \/ AWD)\u003c\/li\u003e\n  \u003cli\u003e2005 Cadillac SRX Base 3.6L V6 (RWD \/ AWD)\u003c\/li\u003e\n  \u003cli\u003e2006 Cadillac SRX Base 3.6L V6 (RWD \/ AWD)\u003c\/li\u003e\n  \u003cli\u003e2007 Cadillac SRX Base 3.6L V6 (RWD \/ AWD)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the GM Sigma I SRX?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2004-2007 Cadillac SRX equipped with the LY7 3.6L V6 engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this resolve downstream P0420 and P0430 diagnostic trouble codes?\u003c\/strong\u003e\u003cbr\u003e Yes, the high-efficiency ceramic core restores target catalytic washcoat reactions, returning closed-loop downstream O2 sensor voltages to factory limits.\u003c\/p\u003e\n\n\u003ch3\u003eThe Cadillac Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to preserve the refined cabin acoustic isolation and precise powertrain management expected from a luxury crossover, this assembly restores OEM exhaust backpressure profiles without creating interior drone or exhaust vibration.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50501741150456,"sku":"DS-E5NGMMVKT","price":245.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-cadillac-srx-2004-2007-3-6l-left-right-1.jpg?v=1789331702","url":"https:\/\/performancechiptuning.com\/es\/products\/catalytic-converter-for-cadillac-srx-2004-2007-3-6l-left-right","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
