1994 Supersport - do I need a Cat Converter?

[Spingo]

I have for some time been thinking of upgrading my exhaust (I have the standard single pipe with Cat on my Caterham), but the one question I have never got round to answering is... if I replaced my manifold & exhaust, would I have to have an exhaust with a catalytic converter to stay legal AND to pass the annual MoT?

My Caterham is a 1994 1.4 SUPERSPORT.

Thanks all!

Is it kit built or factory built. Kit = no cat required, factory = cat required.

Factory...

B*gger.

I was hoping that as an older K series a Cat might be optional only? I'm sure I've read somewhere about a ruling brought in in 1998, but perhaps that applies the 'kit' built cars only?

I don't run a Cat on my factory-built 1997 car and haven't had a problem with emissions at the MOT.

This is a very gray area. Of Caterhams of that vintage (don't know more recent ones), very few indeed are actually "factory built" in DVLA terms.

If I have got it right there were two models that were Low Volume Type Approved (LVTA). The 1.4k series and the VXI.

So it is poss that your factory built 1.4 is actually factory built and comes up in the MoT system as needing a cat.

Have you asked your friendly MoT teting station?

Thanks for replies.

I'm gonna be at my MoT centre this week so perhaps they can advise...
