This catalytic converter is an HD (Heavy Duty) grade product, which means it has a higher precious metal loading compared to the light-duty OEM (Original Equipment Manufacturer) grade version. This enhances its emissions reduction capability and longevity, which is crucial for vehicles that require robust performance under demanding conditions, like the e450 catalytic converter. The substrate is an 8" diameter exactly as the OEM part thereby proving the same surface area for optimal performance
