Catalytic Converter

[plbs1234]

I'm having trouble getting my 1986 Caterham with Kent crossflow to pass emissions. I replaced all the ignition parts and added an MSD ignition module. I also leaned out the DCOE 40's. This got me very close to passing, but I need to still get a little cleaner.

 

Has anyone else added a catalytic converter to allow them to pass emissions? If so what converter did you use?

 

Thanks,

Won't the success of a cat depend on why you are failing emissions? If the failure is for the right reasons, then shouldn't almost any cat for a similar sized engine do the job? If you want 'off-the-shelf' then Birkins have a cat available, as would, I assume, Caterham.
