Inspecting the Primary CATs in an Aston Martin DB9

If you are concerned about how a Primary Catalyst failure could lead to the death of the V12 engine in your Aston Martin - this video has something for you. I explain the issue and show you exactly how to visually inspect the condition of the Primary CATs in your own car. Then I check in with Mike from Bamford Rose to get his opinion.
