Yes. Mopar mufflers are OEM Stellantis service parts — the same components installed at the factory — so mounting flanges, inlet/outlet diameters, and body length match your vehicle's exhaust system exactly with no cutting, welding, or adapter hardware required.

Yes. Because Mopar is the official OEM parts brand for Chrysler, Dodge, Jeep, Ram, and Fiat vehicles, using a Mopar muffler cannot be used by a dealer to void your factory warranty under the Magnuson-Moss Warranty Act, unlike aftermarket alternatives.

Mopar mufflers are tuned to the OEM noise, vibration, and harshness (NVH) targets for your specific vehicle, so sound character and drone behavior will exactly match a new vehicle from the factory. Aftermarket mufflers may vary in tone, back-pressure, and aluminized-steel gauge; Mopar units meet the same corrosion and lifespan specifications as the original assembly.

Unlikely, but an exhaust leak at a cracked muffler body or failed seam upstream of the rear O2 sensor can introduce false oxygen readings and trigger codes like P0136 or P0141. Inspect the muffler body and inlet/outlet welds for cracks or holes before condemning the sensor itself.
