ohh
the car was advertised with a chris wilson decat and i was under the impression it was a full decat
but it wasnt and i had no boost gauge, so i fitted a boost gauge to see what the boost was at and it was 1 bar.
i noticed it had a cat in place still and it was the first cat
i wanted this removed so i bought the decat, restrictor ring, manual boost controller and fuel cut defender to fit.
the guide to changing the downpipe i was following was this one

it doesnt really matter to me at the moment because i have other things to concentrate on with the car but i would like to know so when i come to do it when the cars sorted i can do it,
wouldnt removing the 2nd cat to up boost make it hot in the area where the first cat is?
