I am about to install a stainless exhaust system which came in sections. Should a seal be used between the between the componets. It came with a copper gasket to attach to the manifold. I assume this does not get any sealents but should I use any thing incase I ever decide to change a muffler in the future? Does stainless fuse as rusted steel does? Thanks.

No Tahoe Healey you do not need any sealants in the joints of the exhaust system.----Keoke
 
I know a sealant is normally not recomended, but I too have a S.S. system and knowing it's harder than mild steel, was concerned that the clamps might not seal everything 100% so I used a non-hardening, high temp. gasket compound (Permatex, I think) on the joints (except the gaskets to the manifold). It seals everything very well, and I can still take it apart if I need to. Slider
 
I think you guys are confusing hardness for ductility. Most of the non austenitic stainless steels have a ductility that is close to mild steel. This means that the same mechanical clamping force that seals a Cfe tube should seal a SS tube as well, I am installing a Falcon system on my car and use no sealants just good new clamps and hangers. Just my 2 cents worth. Skip
