Has anyone got any tips on how to seal my cat onto the manifold properly? It's welded to the silencer on one end and has 2 slits on the other end. The inner diameter is 51mm as is the outer diameter of the manifold but I still get it blowing a bit. Exhaust paste seems to get squeezed off and crumbles. Any tips?

HT Silicone sealer does the trick on my exhaust header / cat connection - it is a simple sliding fit when dry but the silicone sealer just makes up the difference and is surprisingly gas tight. Just bear in mind that you will need the cat friendly stuff

^ thats the stuff to use, especially on stainless exhausts!

Never heard of it. Is it the stuff used for head gaskets? Where can I get hold of it or what's it brand name please?

Anyone? A brand name or anything. I don't know what I'm looking for here.

silicone exhaust sealer on google gives this
