I have a classic car which has a three-part exhaust manifold which "telescopes" together - but I do not know how it was sealed or whatever jointing was used (but no longer available anyway).

The problem therefore is what can I use for jointing, which would then require the thee parts to be pressed together as the whole asssembly as it is slid onto the studs.

Can anyone suggest a compressable material - or a very high temperature silicone type sealant which would handle the heat but remain sufficiently flexible to allow for thermal expansion and contraction etc.

Best suggestion gets a (slow) ride in a sleeve valve Daimler!!!

Whilst I can't help with the answer, have you tried looking online for an owner's club/forum?

That won't work, it is just an RTV "silicone" type instant gasket.

Whilst it is fantastic on rocker covers, sumps etc, it will not work on an exhaust.

TBH, I can't get my head round the concept of a telescopic exhaust manifold, can you get a pic?

A tube of exhaust pipe sealant is available at most motor factors
White, helps the pipes slide together then expands to fill any gaps when hot
