PROCUREMENT NOTE / FIRST ORDER
Compare quotes from up to 3 factories
FREE basic specification and sourcing-requirements review
Eligible first orders may receive up to 3%
Eligibility applies to qualified business buyers and is confirmed after we review your product, quantity, destination, and sourcing requirements. Final savings depend on supplier confirmation, product type and order value.
Independent automotive parts sourcing. Define vehicle application, order unit and destination so we can request factory quotes on converters used as emissions replacements—not delete pipes or sensor defeat parts.
Request factory quotes| Known | Confirm with supplier |
|---|---|
| Vehicle year, engine family or VIN, installed position and quantity by position | Application listing for that converter reference, packing contents and delivery terms |
| Inlet/outlet diameters, overall length and whether an oxygen-sensor port is required | Whether the offer is a weld-in shell or a flanged assembly, plus excluded gaskets or heat shields |
| US destination state and intended on-road or off-road use statement from the buyer | Any Executive Order, part number and vehicle list the supplier claims for that exact converter |
Record model year, make, model and engine family or VIN. A catalog title such as universal catalytic converter does not prove the shell belongs on that engine. Leave unresolved chassis codes visible rather than guessing a bank or body style.
State bank 1 versus bank 2, front versus rear, inlet and outlet diameters, overall length, flange or pipe style, and oxygen-sensor bung location. Matching appearance of a car catalytic converter photograph is not confirmation of the pipe layout.
Give pieces by vehicle position, not a vague kit count. Ask which catalytic converter gasket, clamps or heat shield the quotation includes, and whether a remanufactured unit would carry a core charge if that supply path appears.
Provide destination ZIP or state and a requested delivery window. Application documents and freight Incoterms stay on the quotation; they are not implied by this website.
Read the aftermarket RFQ checklist before comparing shells, or open the inquiry catalog.
No. Ask for the vehicle application listing, OE reference used only for identification, mounting position and interface dimensions. A replacement catalytic converter label without those fields stays pending.
No. A target budget in USD per piece or for the whole order is optional. Quantity, destination and specification still define the request even when you have not collected competing prices.
No. Sample timing, production release and transport to the destination ZIP belong in the supplier response. This service does not publish stock or factory calendars.
No. Test reports, supplier declarations and warranty wording apply only to the stated converter, batch and destination. They do not become Catalystbay Sourcing credentials.
Resolve converter construction (cylindrical, oval, sensor-port or direct-fit), vehicle-position quantity and destination state. Flag delete-pipe or emissions-defeat requests as out of scope.
Ask manufacturers for comparable quote scope: substrate or assembly description, included hardware, packing unit, sample terms and documents tied to the offered part number.
Align unit cost, freight, taxes and service fees before ranking offers. Compare new versus remanufactured statements only when the supplier discloses that status.
Record the accepted specification, remaining open questions and each party’s shipment responsibility. Unverified CARB or EPA language stays unmarked as approved.
Include quantity, order unit and destination. Optional budget and supplier preference can travel with the same inquiry.
