Exhaust gasket between cat and middle??

[Cookson]

Guys, is there a gasket between these joints? Or is it just a case of slapping on the fire putty?

fire putty should be banned, its crapper than crap

silicone only!

any recomendations fred?

Assuming not the stuff my dad seals the bath tub to the wall with?

You can get high temp silicone sealant from halfords or a motor factors most of the stuff Ive seen is made by loctite.

Does that stuff hold up well? Never actually used anything so far that lasts longer than a day!

I use cheapo high temp black silicone sealant from the motor factors - £3 for a tube that fits into a caulk gun. Rated to 350deg+ or something, works perfectly and never had a problem. Whereas the firegum/paste s*hite just cracks and starts blowing

gungum, fire weld etc etc all s**t and not worth touching

Just go to a local motor factors and ask for high temp silicone sealant/gasket - will do the job fine
