I never bothered when fitting mine but heard people saying the cheap kits on flea bay are totally useless.
also due to the decat being larger than the cat it can catch on the gear linkage when in reverse seams to be for me this may be wrong sure someone will verify
On a 172 or 182?
Mine never caught on the gear linkage but early ph1 172's I believe have a different length of cat.

Get a new OE one from renault. You dont want to spend ages messing about at the side of the road getting your cat off, refitting the decat to find its blowing and you have to pull it apart again
