Deteriorating internal ceramic matrices create exhaust backpressure that restricts scavenged gas exit speeds, dulling low-end torque output and triggering recurrent P0420\/P0430 DTCs. Additionally, thermal cycling leads to manifold flange warpage, creating persistent exhaust leaks ahead of the downstream heated oxygen sensors.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement assembly utilizes a high-grade 409 stainless steel outer casing and mandrel-formed tubing engineered to resist corrosion and structural fatigue under prolonged heat cycles. Inside, an optimized flow-through ceramic honeycomb substrate carries an active precious-metal washcoat formulated to oxidize hydrocarbons and carbon monoxide efficiently without choking exhaust flow. Featuring precision laser-cut 4-bolt inlet and 3-bolt outlet flanges, this converter installs directly to factory exhaust hang points and integrates pre-threaded O2 sensor bungs matching OE locations.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 × Direct-Fit Stainless Steel Catalytic Converter\u003c\/li\u003e\n  \u003cli\u003eInstallation Hardware and Gasket Kit\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: solid font-size: min-width:\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;\"\u003e1998-2005 Lexus GS\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\u003e2JZ-GE\u003c\/strong\u003e \/ \u003cstrong\u003eJZS160\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;\"\u003e225 hp \/ 220 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\u003e1714046030\u003c\/strong\u003e, \u003cstrong\u003e1714046080\u003c\/strong\u003e, \u003cstrong\u003e674-642\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\u003e1998-2005 Lexus GS300 Base Sedan 3.0L Inline-6 (2JZ-GE)\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 JZS160 GS?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1998-2005 Lexus GS equipped with the \u003cstrong\u003e2JZ-GE\u003c\/strong\u003e 3.0L engine. \u003cstrong\u003eNote: This unit is not legal for sale or use in California, New York, Colorado, or Maine, and does not fit 4.0L\/4.3L V8 GS models.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eAre new gaskets and mounting hardware included for install?\u003c\/h4\u003e\n\u003cp\u003eYes, the converter comes packaged with mating flange gaskets and standard hardware required for bolt-on installation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Lexus JDM Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to match the high-revving characteristics of the inline-six platform, this unit maintains factory acoustic damping while ensuring free-flowing exhaust scavenge lines for reliable daily operation.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67916979896568,"sku":"DS-E4B45BE4W","price":226.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-lexus-gs300-1998-2005-3-0l-1.jpg?v=1793478955","url":"https:\/\/performancechiptuning.com\/products\/catalytic-converter-for-lexus-gs300-1998-2005-3-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
