Failed MOT on emission. Looking for catalytic converter
Failed MOT on emission. Looking for catalytic converter
Hello, I have Audi S2 Avant Aby 93. It does not have cat, only strait pipe so I fail on MOT for emissions. Now since my exhaust fumes are really bad I am looking for catalytic converter and want to ask what option would be better. To find standard cat, universal, cheap sport one or what?
I did that for a while, until I got bored of laying cramped under the car before every MOT, and then welded in a sports cat. the cheaper ones probably will need replacing every 5yr or so, not that much active material to begin with and when that degrades it will probably fail MOT. btdt.
