Frequently asked

How do I know a part will fit my car?

Enter your registration above and we cross-check against the TecDoc catalogue to narrow the list to catalytic converters listed against your vehicle. Specifications can still vary between trim levels and engine variants, so we recommend confirming the part dimensions against your existing component before fitting.

What brands do you stock?

We stock established manufacturer brands sourced through trade channels. The brand row at the bottom of this page shows which manufacturers we carry for catalytic converters. We don't sell unbranded parts.

How quickly will my order arrive?

Most orders dispatch from our Northampton warehouse within 1–2 working days. Free standard delivery on orders over £40 to most UK mainland locations.

What if the part doesn't fit?

Please check our returns policy for the current terms. If you're unsure about fitment for your specific vehicle variant, please contact our team before ordering using the details at the bottom of the site.

Can I check fitment before ordering?

Yes — every product page shows whether the part is listed against your selected vehicle. Where multiple sizes exist for the same vehicle, the dimensions are shown so you can compare against your existing part. If you're unsure, contact our team for help confirming the right option.
