Over time, thermal cycling and exhaust pulses from the \u003cstrong\u003e2GR-FE\u003c\/strong\u003e engine degrade the internal ceramic monolith, causing cell sintering, carbon fouling, and reduced precious metal conversion efficiency. This thermal fatigue triggers downstream oxygen sensor faults (such as DTC P0420 or P0430), increases tailpipe emissions, and creates internal exhaust flow restrictions that hinder engine scavenging efficiency.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a bolt-on replacement, this rear catalytic converter assembly restores factory exhaust flow dynamics and emissions conversion without cutting or welding. Constructed with a heavy-gauge, corrosion-resistant stainless steel body, the unit houses a high-efficiency ceramic substrate loaded with an EPA-compliant precious metal washcoat to effectively oxidize hydrocarbons and carbon monoxide. Precision-stamped flanges align directly with factory hangers and intermediate piping, while included installation hardware and replacement crush seals guarantee an airtight seal against exhaust leaks.\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;\"\u003e2005-2017 Toyota Avalon\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\u003e2GR-FE\u003c\/strong\u003e 3.5L V6 \/ \u003cstrong\u003eXX30\u003c\/strong\u003e, \u003cstrong\u003eXX40\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;\"\u003e268 hp \/ 248 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\u003e2005-2012 Toyota Avalon (XX30) 3.5L V6 (XL, XLS, Touring, Limited)\u003c\/li\u003e\n  \u003cli\u003e2013-2017 Toyota Avalon (XX40) 3.5L V6 (XLE, XLE Plus, XLE Premium, Touring, Limited)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the XX30 and XX40 Avalon?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2005-2017 Toyota Avalon equipped with the \u003cstrong\u003e2GR-FE\u003c\/strong\u003e 3.5L V6 engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this converter clear downstream catalyst efficiency trouble codes?\u003c\/strong\u003e\u003cbr\u003e Yes, assuming the engine's air-fuel mixture, ignition timing, and oxygen sensors are functioning within factory specifications.\u003c\/p\u003e\n\n\u003ch3\u003eThe Toyota Longevity Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to preserve the refined acoustic isolation and smooth power delivery expected of Toyota's flagship sedan, this assembly maintains correct exhaust backpressure parameters without introducing cabin drone or rasp under acceleration.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50501746786552,"sku":"DS-E3URQGGXV","price":233.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-toyota-avalon-2005-2017-3-5l-rear-1.jpg?v=1789331897","url":"https:\/\/performancechiptuning.com\/products\/catalytic-converter-for-toyota-avalon-2005-2017-3-5l-rear","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
