Close-coupled converter
For the close-coupled converter line, document regulatory application: State destination market, engine, production date and emissions label evidence. Add required quantity, included hardware, packing and destination.

Exhaust System · decision page
Catalyst assemblies are market- and regulation-sensitive exhaust components. A quote must identify the legal destination, engine, position and complete pipe boundary.
Decision matrix
Every field should describe the specific requested item, not merely the vehicle family.
Reference evidence gate
No OE number is published on this page because the reviewed public sources did not safely resolve every market, build-location, powertrain and production split.
Do not represent a replacement catalyst as emissions-compliant, road-legal or equivalent to an original unit unless the exact destination requirement and supporting certification are confirmed in writing.
Request scope
Similar buyer terminology can describe a different kit, side, finish or packing scope.
For the close-coupled converter line, document regulatory application: State destination market, engine, production date and emissions label evidence. Add required quantity, included hardware, packing and destination.
For the underfloor converter line, document exhaust position: Name manifold, close-coupled or underfloor position and record adjacent pipe sections. Add required quantity, included hardware, packing and destination.
For the converter and pipe assembly line, document interfaces: Document flange patterns, overall geometry, sensor bung count and heat-shield mounts. Add required quantity, included hardware, packing and destination.
Continue the buying path
Return to the complete system index, prepare a stronger evidence pack, compare an adjacent request line or continue to a matching POPXA company catalogue page where one exists.
Exhaust assemblies are shaped by engine, wheelbase, emissions market and sensor position. Quote the complete section boundaries rather than a broad exhaust name.
Buyer guidePrepare vehicle records, reference photos, dimensions, connector views and clear filenames before quotation.
Related lineThe term manifold may describe a bare casting or a catalyst-integrated assembly. The inlet ports and downstream boundary must be shown together.
Related lineA rear silencer is a long, position-specific shipment item. Use underside photographs and measured hanger coordinates rather than a generic body shape.
Buyer questions
Use these answers to prepare a clearer first request.
No. Send the production period, market, powertrain or drivetrain evidence and the part-specific checks listed on this page.
Record regulatory application, exhaust position, interfaces, commercial and freight together with quantity, packing, destination port and the preferred Incoterm.
The reviewed public evidence did not safely resolve all market, build-location, powertrain and production splits. Send the installed-part and vehicle evidence so a candidate reference can be checked before quotation.
Build a traceable request
Include vehicle generation or production period, market, engine or hybrid designation, drivetrain, part reference or photos, position, quantity, packing and destination. A listing is not automatic fitment or availability confirmation.
