td4 cat

Hi All,
Who supplies a straight through exhaust pipe with no cat as mine has a hole in it and need it sorting for the Mot, garage has said that I dont need a cat on a diesel.
Cheers

You'll need to fabricate something.

is it not possible to take your cat off knock the middle out and just weld up the hole

Yes do as Mat says if poss.

I had mine nicked by the pikeys so I had a straight chrome pipe fitted for 60 quid by Custom Exhausts in Doncaster near me.

Click to expand...

A friend of mine who works for a certain well known tyre and exhaust place and does the MOT testing says the CAT is now part of the test as in visual inspection(must be there) as I myself was looking at a de-cat but after herering that didn't bother not sure how true this is but just what I'd heard maybe someone could shed light further on this

if thats true do what i said above about taking it off and knocking the middle out... if you can also put a pipe through the middle of cat once its knocked out weld up the ends and then refit that way the cat is a straight through pipe but no one knows any difference

this is the relevant section of the manual

Check

3 On petrol engine vehicles that qualify for a full
catalyst emissions test, check the presence of​

the catalytic converter.

Fail
3. A catalytic converter missing where one was​

fitted as standard.

So as I understand it its only a petrol that will fail if a cat was fitted not a diesel
