Pricing & Identifying Subaru Catalytic Converters

Posted: January 3, 2023

Over time we have learned more about Subarus- and Subaru has also done a much better job improving its identifying systems for its catalytic converters. They have started to include serial codes or part numbers on their cats, but you have to know where to look. Sometimes these codes have been located under the shields or are hidden behind the shield altogether.

Removing the shields (do not throw them away, sometimes, they may be stamped on there) will give you a higher likelihood of finding the serial codes easier and faster.

Most Subarus Have Two Catalytic Converters

If not most, many Subarus have two catalytic converters on them. The first unit will be the main cat, and it will be followed by a pre-cat, both of these units have excellent scrap value, and by finding the serial codes, you could sometimes double the quoted price of your cats.
