    best way to seal de-cat to turbo?

    just wondered what the best way to seal the pre-cat to the turbo as i have a tiny blow from there.i have a decent flexi and 2nd cat with new gaskets so thinking it can only be pre-cat to turbo?there is a gasket there but had simlar problem on my old car.is it best to just buy a new gasket and try get a tight seal with a decent clamp?do people do with out the gasket or would that be worse at a guess.

    Wasn't aware there was a gasket, but always just put a smear of assembly paste of gel round the mounting faces first. Never had an issue. yet.

    I located the pre cat in to the turbo then put jack under the bottom of it jacked it up gently till it was tight then tightened up the clamp seemed to do the trick with mine, dont know if that will help you? I never used and gaskets either.
