Exhaust Paste and Cats

Hi Guys

My exhaust is leaking at the joint at the back of the cat and my question is… Is it safe to use some exhaust paste to seal it ?

Not sure because of the cat, sorry if its a no brainer [:)]

 

Depends where it’s leaking from, if it’s at the joint between the flanges, you really need to undo the joint and re make it. Paste can only ever be a stop gap [excuse the pun[:$]]
