Direct-Fit Catalytic Converter Assembly for 2013-2019 Jeep Grand Cherokee
What it Does: Restores exhaust flow dynamics and clears catalyst efficiency diagnostic trouble codes (P0420/P0430) on the 3.6L Pentastar platform by replacing degraded factory catalyst monoliths.
The Stock Grand Cherokee Substrate Breakdown
Factory catalytic converters on the WK2 platform are susceptible to internal substrate degradation over prolonged duty cycles. Continuous thermal expansion cycles cause washcoat sintering, micro-fracturing of the ceramic core, and reduction of noble metal surface contact. Over time, restricted exhaust pathways increase backpressure against the cylinder heads, driving up exhaust gas temperatures (EGTs) and diminishing low-end torque output, and triggering check engine lights.
The Engineering Solution
Engineered as a direct bolt-on assembly, this unit features a heavy-gauge 409 stainless steel housing designed to withstand extreme thermal stress, road debris impact, and structural corrosion. Inside, an emissions-grade ceramic honeycomb substrate delivers high-efficiency catalytic reduction with minimal exhaust restriction. Precision-formed flanges and integrated factory-profile mounting brackets ensure an accurate seal to stock exhaust manifolds, retaining factory oxygen sensor bung locations without requiring cutting or custom welding.

Common Questions
Will this catalytic converter assembly fit my 2016 Jeep Grand Cherokee 3.6L?
Yes, this direct-fit assembly is built for all 2013-2019 Jeep Grand Cherokee WK2 models equipped with the 3.6L Pentastar V6 engine.
Does this fit the Hemi or EcoDiesel Grand Cherokee?
This assembly is engineered specifically for the 3.6L Pentastar V6 engine platform and its factory exhaust manifold flanges.
What is included in the box?
The kit includes both the left and right side catalytic converter assemblies along with direct-fit mounting hardware, clamps, and installation gaskets.
Is any cutting or welding required for installation?
This is a direct bolt-on replacement with precision-formed flanges, factory-profile mounting brackets, and stock oxygen sensor bung locations, so no cutting or custom welding is needed.
What material is the converter housing made from?
The housing is constructed from heavy-gauge 409 stainless steel with an internal ceramic honeycomb substrate for durability and corrosion resistance.
