It's one cat not two. Just order the 172 decat from NW performance mine was a single lambda sensor cat but I fitted a decat with 2 sensor holes, I just needed to buy a bung.
If it's a w-reg it should be a single lambda sensor cat. You can tell because there will be no sensor just after the cat just before it joins the mid section.

it IS 2 cats, but you only need one decat pipe. you'll need to look closer and see if you have an after-cat lambda sensor or not. There is a difference in length between the 2 exhausts. All good after market exhaust systems have adjustment at the end that joins the cat to account for this

You have a twin barrel cat but you only need to buy 1 decat to replace it.
This is an example of the decat you want to buy http://www.k-tecracing.com/show_product.asp?id=2034&appid=2
Look at your exhaust and see if there is a lambda sensor after the twin barrel part (I am guessing you haven't with being on a W plate).... if there is NOT then go for the single lambda decat in the list.

i was told not to bother decatting it, apparently the ph1 cat is free flowing anyway, so pointless fitting a decat, ur not going to see any gains. spend your money on matched inlets instead, the ph1 casts are rubbish so you will see more gains with inlets.
ITB'd MK1
no, all ph1's were twin cat. (give or take a few odditys)
Canvey mate, you had your Clio long?
PH1 172
Not far at all mate. 5 years it will be on the 7th August
How long you had your one?This
PH1 172
That's a pain in the backside....at least you will have the knowledge that all the belts and dephaser has been done
I had to get the gearbox replaced 2 months after ownership :dead:

you're incorrect, your car has been put together from random bits. the first ph1's were single LAMBDA
Mk3 clio 1.5
change over model are often made with random parts so you can sometimes get a bit of everything, really annoying when your wanting to do a engine swap
PH1 172
Twin barrel cat all through the life of the ph1 mate especially from the start. Some later ones had the 2 sensors and the odd few towards the end may have had single cats but that may have only been the time during swap over to the new shape.
