Catalytic Converter Universal

A catalytic converter is an essential emissions control device, and our universal-fit selection gives you the flexibility to replace a failed converter or upgrade your exhaust system when a vehicle-specific part isn't available. These units are designed for custom fabrication—they don't bolt directly to factory exhaust hangers, so some welding and pipe-fitting is expected. By offering multiple diameters, cell counts, and substrate options, the collection lets you match a converter to your engine's displacement, power level, and local emissions requirements.

  • Inlet/outlet diameter and overall length—match to your exhaust tubing size
  • Cell count and catalyst loading—higher cell counts often improve efficiency; lower counts can support higher flow for performance builds
  • Substrate type—ceramic cores are common for street use, while metallic substrates handle extreme heat and vibration in racing applications
  • Oxygen sensor bung placement—verify whether you need a pre-cat or post-cat sensor port
  • Compliance—confirm that the converter meets the emissions standards in your region before purchase

If you're tackling a custom exhaust, replacing a rusty factory catalyst, or building a track-only setup, a universal converter gives you the core component to finish the job. Check each product listing for exact dimensions, cell count, and included hardware.
