Over time, internal sintering limits the catalyst's oxidation-reduction capabilities, resulting in persistent check engine lights (P0420 and P0430 diagnostic trouble codes), increased emissions, and substrate breakdown that produces rotten-egg sulfur odors or rattles from fractured internal baffles.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact OEM dimensional tolerances, this front and rear assembly features a high-grade stainless steel outer shell designed to resist road-salt corrosion and thermal fatigue. Inside, a high-flow ceramic honeycomb substrate coated with balanced precious metal loadings delivers optimal conversion of hydrocarbons, carbon monoxide, and nitrogen oxides. Precision robotic-welded flanges bolt directly to the factory manifolds and exhaust tubing, complete with pre- and post-catalyst oxygen sensor bungs to maintain accurate air-fuel trim data without cutting, welding, or ECU retuning.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x Front \u0026amp; rear catalytic converter assembly\u003c\/li\u003e\n  \u003cli\u003eMounting bolts\u003c\/li\u003e\n  \u003cli\u003eInstallation mounting hardware\u003c\/li\u003e\n  \u003cli\u003eExhaust seals\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;\"\u003e2013-2017 GMC Terrain\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\u003eLFX\u003c\/strong\u003e 3.6L V6 \/ \u003cstrong\u003eTheta\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;\"\u003e301 hp \/ 272 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\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2013-2017 GMC Terrain (SLE, SLT, Denali) 3.6L V6 Front \u0026amp; Rear 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 Theta Terrain?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2013-2017 GMC Terrain equipped with the \u003cstrong\u003eLFX\u003c\/strong\u003e 3.6L engine.
