lol!

clean the mating surafces with a wire brush, you may need new gaskets so try and not damage the old 1's, i always use exhaust paste on the joints aswell.

Also spray some good penetrating fluid on the old nuts a good few hours if not the day before going at them.

A decat on a 172 is a pain I've heard??

i shall let you know! I think the bolts are tucked up behind the bulkhead area, I haven't looked for a while.

I was more worried about removing the lambda sensors tbh, dont want them to snap!

I couldn't find a guide anywhere, I'll keep looking.

Run the car for 2/3 minutes before you try to remove the Lambda, should free up nicely. Just don't keep it running too long or you'll burn yourself!

you can buy the mesh ring seperately (Bosal 256781; about £5) but will also need the cat-to-system gasket (256008)

for what little you'd save, may as well buy the NWP kit for all new nuts/bolts, and buy the cat-to-system gasket seperately. the nuts/bolts will be in a state if they're original anyway

Loctite 5920 (copper silicone) is probably best bet for sealing the joints; the paste ones just crumble away after a little while
