In general, prices range from economical aftermarket options to pricier OEM replacements, with labor costs adding to the total. You can expect OEM units to run roughly $800 to $1,600, aftermarket direct-fit parts around $200 to $500, universal aftermarket units about $50 to $300, and used or salvaged converters typically $100 to $350, plus installation labor of about $100 to $300.
The Honda Prelude spans several generations (from the 1980s through 2001), and prices vary by model year, engine type, emissions requirements, and your location. Emissions rules, especially in California and other CARB states, influence whether a unit must be CARB-compliant. This guide lays out typical price ranges and buying options to help you budget for a replacement or upgrade.
Price ranges and options
Prices depend on the type of converter you choose—OEM, aftermarket direct-fit, universal, or used. Here is a quick breakdown to help you compare your options.
- OEM direct-fit catalytic converter (Honda Genuine or dealer-listed part): typically around $800–$1,600, depending on year, engine code, and regional availability.
- Aftermarket direct-fit catalytic converter: commonly $200–$500, with higher-end or high-flow designs often $350–$900.
- Aftermarket universal catalytic converter: often $50–$300, but installation requires fabrication and may affect emissions compliance and fitment.
- Used or refurbished catalytic converter: usually $100–$350, depending on condition and salvage availability.
- Labor for installation: typically $100–$300, depending on shop rates, vehicle access, and whether additional exhaust work is needed.
Note: These ranges are approximate and vary by year, region, supplier, and whether the part needs CARB compliance for on-road use. Always verify part number compatibility with your Prelude’s year and engine, and confirm emissions compliance with your local regulations before purchase.
Direct-fit vs. universal and buying considerations
Choosing between OEM, aftermarket direct-fit, or universal options affects fit, legality, and service life. OEM units are designed for exact fit and guaranteed compatibility but cost more. Aftermarket direct-fit parts offer a balance of price and fit, while universal converters are cheaper but may require cutting, welding, or additional fabrication and may not meet local emission standards.
When evaluating options, consider your engine code (for example, the Prelude’s H-series variants), local emissions rules, warranty expectations, and the potential impact on performance and fuel economy. If you plan to sell or register the car in a strict emissions region, CARB-compliant direct-fit units are often the safer choice to avoid failures during inspections.
Where to buy
You have several sourcing options, from OEM dealers to aftermarket retailers and salvage yards. Before purchasing, compare part numbers, warranty terms, and return policies. The list below highlights common avenues.
- Honda dealership or authorized parts retailer
- Auto parts stores (e.g., AutoZone, NAPA, O'Reilly)
- Online retailers (RockAuto, PartsGeek, Amazon, eBay with reputable sellers)
- Salvage yards or pull-a-part facilities
Tip: If you’re unsure which part fits your Prelude, bring your VIN or engine code to verify compatibility. For emissions compliance and long-term reliability, professional installation is often worth the extra cost.
Summary
For a Honda Prelude, catalytic converter pricing varies widely by part type and emissions requirements. Expect OEM replacements to run roughly $800–$1,600, aftermarket direct-fit parts around $200–$500, universal units about $50–$300, and used options $100–$350, with labor typically $100–$300. Verify the exact part number for your year and engine, and ensure any chosen unit complies with local emission regulations. Shopping around and balancing cost with emission compliance will help you choose the best option for your Prelude.
