I've posted previously about my Puma 1.7 failing its MOT on emissions. The tester says it needs a new cat - I had some useful advice on this forum about possible alternative problems, but they're all beyond my ability to test. I tried a local exhaust specialist, only to be told that he couldn't replace the cat because he didn't have the right tool to remove the manifold - that just baffled me even further. Can anyone recommend a Puma specialist who could sort this out for me? Ideally in the St Albans area, but any useful contacts would help.
