Frequently Asked Questions: OE 14310475-00
How do I know this catalytic converter will fit my BYD Seal 06 DM-i?
Fitment on a part like this comes down to matching the shape and mounting points exactly, not just the model name. Have a look at the photographs on this page and compare the flange positions, pipe angles and mounting brackets against the unit currently under your car. If the layout matches what you see underneath, you are looking at the right part.
What if the number on my old catalytic converter is not 14310475-00?
Check the number stamped on the part you are removing before ordering. Underbody exhaust components like this one are matched by that reference rather than by trim level or engine size, so a different stamped number means a different unit. If yours does not match 14310475-00, that stamped figure is what you need to work from to find the correct replacement.
How will a part this size be delivered?
Delivery time is confirmed with your quote. The packaging details are shown on this page. Before you order, check the fitment table on this page to confirm the OE number 14310475-00 matches the part you are removing, so you know the unit heading your way is the correct one for your car. The shipping cost is confirmed with your quote.
Where does this part actually sit on the car?
This is an underbody component, fitted beneath the car as part of the exhaust run rather than under the bonnet. It combines the catalytic converter with the front pipe as one assembly. If you want to cross check it against parts catalogues that use a different reference, it is also listed under TA40-1203050CA, which can help confirm you are looking at the same unit from another source.
