Probably a stupid question, where are the cats located on the exhaust system? I have looked at it and can see there are 3 parts to it, down pipe, mid and rear. Which section has the cat?

That 3.5% and 1200 ppm HC's rings a bell.

However, have just checked the emissions sheet and I had worse case 1.37 co and 82 ppm HC, but I think we just ran that thru after as a check.

So I reckon we did a non cat test.

Thanks for your expert help Paul.

:cool:

When I took my Zed in for its mot, they tested the cats though it was a '91 car.

I asked them whether it was necessary since it was pre '92.

Their reply was any car fitted with a cat, irrespective of it's age has to be tested for it's efficiency.

Since the car passed it's test I did not argue the case.

Likewise I had the same responsewhen I said but it's pre 92 but it passed as well.

 

Got rid of the bloody things now with de-kitten pipes so we'll await MOT next year !!

wouldn't wory about the mot.

My inlet valves are fooked and I'm kicking out just under 3000 ppm Hydro Carbons.

Still passed
