- What is the difference between a direct-fit and a universal catalytic converter?
- A direct-fit converter like the Catco 1535 is shaped and flanged for a specific vehicle, so it installs with hand tools and no fabrication. A universal unit is a generic body that needs cutting, welding and often new pipe to fit. Direct-fit costs more but saves labor and avoids fitment errors.
- Does Catco make converter and pipe assemblies?
- Yes. The Catco 5309 combines the converter with the connecting pipe in one piece, which suits vehicles where the original pipe has rusted through at the same time as the converter. It avoids buying and joining two separate parts.
- Are Catco converters legal for use in California?
- Catco sells both 49-state and California-compliant units, and the two are not interchangeable. Check the emissions certification on the specific part number against your state's rules before buying. A 49-state converter installed on a California-registered vehicle will fail inspection.
- What warranty does Catco offer on its converters?
- Catco backs its converters with a limited warranty that varies by part and application, typically covering structural integrity and emissions performance for a set period. Keep the purchase receipt, since warranty claims require proof of purchase and often proof of proper installation.
- How do I pick the right Catco converter for my vehicle?
- Match by year, make, model, engine size and drivetrain, because the same model can use different converters across trim levels. Also confirm whether your vehicle is California or federal emissions certified. The part number stamped on the original converter is the most reliable reference.
- Are there Catco discount codes?
- Deal.ai checks what Catco products actually cost at every store, so a real markdown shows on this page as a deal as soon as it starts, and each product's page has its price history to tell a sale from its usual price.
