Catalytic Converter for Dodge Charger (2011-2020) 5.7L

Direct-Fit Stainless Catalytic Converter Pair for 2011-2020 Dodge Charger (LD)

What it Does: This left and right direct-fit catalytic converter set replaces worn factory front converter pipes on the 2011-2020 Dodge Charger (LD) EZH 5.7L HEMI V8 to restore exhaust flow and emissions compliance.

The Stock Dodge Charger Catalytic Converter Failure

On high-mileage LD Chargers equipped with the EZH 5.7L HEMI V8, sustained exhaust gas temperatures and thermal cycling fatigue the OEM ceramic monolith. Over time, the internal substrate fractures, breaks loose from its mounting mat, or suffers washcoat poisoning from oil consumption and cylinder misfires. Once the core degrades, oxygen storage capacity drops, triggering P0420/P0430 catalyst efficiency faults while broken substrate fragments restrict exhaust flow and create metallic rattling.

Common Symptoms of a Failing OEM Catalytic Converter

• Check Engine Light / Catalyst DTCs: Stored P0420/P0430 codes caused by downstream O2 sensors mirroring upstream switching patterns.
• Metallic Exhaust Rattle: Audible rattling beneath the floorboards at idle or deceleration from a fractured ceramic honeycomb substrate.
• Backpressure & Flow Loss: Sluggish throttle response, elevated exhaust backpressure, and failed emissions testing due to clogged converter cells.

The Direct-Fit Stainless Exhaust Solution

Constructed with a corrosion-resistant stainless steel body (8-inch length, 5-inch height) and factory-routed piping, this complete left-and-right converter pair resists rust and thermal cracking. Inside, an OBD-II compliant ceramic honeycomb substrate coated with precious-metal catalysts converts HC, CO, and NOx without restricting V8 exhaust scavenging. Factory-style manifold flanges, integrated O2 sensor bungs, and rear clamp connections ensure a direct bolt-on installation with zero cutting or welding.

Frequently Asked Questions & Fitment Warnings

Does this fit the LD Charger?

Yes. This is a direct fit for the 2011-2020 Dodge Charger equipped with the EZH 5.7L HEMI V8 engine. Not compatible with 3.6L V6, 6.4L, or 6.2L supercharged engines. EPA (federal) compliant only—not CARB approved and not legal for vehicles registered in California, New York, Colorado, or Maine.

Will this clear P0420/P0430 codes, and are O2 sensors included?

Yes, when caused by a worn catalyst, and no, O2 sensors are not included. Installing fresh left and right units restores conversion efficiency to clear P0420/P0430 codes, provided you inspect for exhaust leaks and transfer or replace your existing O2 sensors.

Is mounting hardware included for installation?

Yes, clamps and flange bolts are supplied. The kit includes two rear exhaust clamps and four flange bolts with nuts; soak seized OEM fasteners with penetrating oil, let the exhaust cool completely, and torque joints evenly before checking for leaks.

The Dodge Performance Standard

Built to maintain proper V8 exhaust scavenging and backpressure balance, these direct-fit converter pipes restore crisp throttle response and dependable emissions operation on your LD Charger. Every joint matches OEM flange geometry for leak-free street and fleet durability.
