MBFinlay Posted January 31, 2022 Share Posted January 31, 2022 What emission "class" does the Mb6 belong to? i have 1997 model. I'm looking to buy a new universal catalytic converter. I need to know which kind is enough to pass the emissions. Some converters are for pre-obd-II etc. I'm not even sure if Mb6 is technically obd-II? Also do you guys in UK use Euro 2, Euro 3, Euro 4 etc. class for emissions? My MB6 is a 97 so idk if its euro 2 or euro 3? Does any catalytic converter with o2 sensor fitment suffice?

KiNK43 Posted January 31, 2022 Share Posted January 31, 2022 Mb6 has a single O2 sensor. Pre cat and it's in the manifold. As for the answer to your question I do t know. However aftermarket cats are available I baught one last year for aerodeck to pass MOT Quote Link to comment Share on other sites More sharing options...

I bought the car with aftermarket exhaust system including the manifold (dc sports 4-1) so i've always used aftermarket catalytic converter and the O2 sensor is in the converter. The converter naturally after the manifold under the car because of aftermarket parts. But i always thought the EK civics had the catalytic converter mated with the manifold up-front and MB civics had it more traditionally positioned under the car after manifold? I wonder if it affects emissions when it's all situated in different place... Does any basic cheap aftermarket/universal catalytic converter work for you guys? Any problems at MOT?

KiNK43 Posted February 1, 2022 Share Posted February 1, 2022 They work yes but generally dont last long. May get a few years out of one. Quote Link to comment Share on other sites More sharing options...
