In the 3.6L \u003cstrong\u003ePentastar\u003c\/strong\u003e V6, high exhaust gas temperatures accelerate honeycomb structural breakdown and internal fracturing. This creates exhaust backpressure spikes, causes oxygen sensor waveform discrepancies, triggers catalyst efficiency fault codes (P0420 \/ P0430), and leads to unburnt fuel smells or exhaust rattling under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a bolt-on assembly specifically for all-wheel-drive drivetrains, this unit incorporates a heavy-duty stainless steel outer shell containing a high-efficiency ceramic catalyst substrate loaded with precious metals. It features precision-machined 4-bolt connection flanges and factory-positioned O2 sensor bungs to maintain accurate downstream air-fuel monitoring without cutting, welding, or ECU re-calibration. The construction resists structural fatigue and thermal cycling, reestablishing proper exhaust scavenging and factory backpressure parameters.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x Catalytic converter assembly\u003c\/li\u003e\n  \u003cli\u003eMounting bolts\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;\"\u003e2011-2017 Chrysler 300 AWD\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;\"\u003e3.6L Pentastar V6 \/ LD\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;\"\u003e292 hp \/ 260 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\u003cstrong\u003e4W2306R\u003c\/strong\u003e\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\u003e2011-2017 Chrysler 300 3.6L V6 AWD (4-Bolt Flange)\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 LD 300?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2011-2017 Chrysler 300 equipped with the 3.6L \u003cstrong\u003ePentastar\u003c\/strong\u003e engine. \u003cstrong\u003eFits AWD models with the 4-bolt flange connection only; does not fit RWD models.
