    Few q's RE S/S Precat & sprots cat.

    Right, i'll be fitting a s/s precat & sports cat this week to my LET, anyone know of a good guide?

    I've read that its best to use sillicone to seal the joint at the front of the pre cat as standard exhaust seal doesnt seal on stainless, is this true?

    Can i re-use the old gaskets etc, the bolts are rusted and will be replaced with galvanised anyway.

    no sealant should be used before the cat. easier to fit the pre cat without a gasket and depends on the condition of the pre cat to sports cat gasket if it needs to be changed or not. why not fit a new one anyway?
