No mate, no need gaskets just what I do is to apply a coat of high temp copper paste (Molycote) on the turbo flage and if you like you can use exhaust pipe sealant on the joints. I never used though and I have no leaks (I only use Molycote so I can disassembly the thing easily when I need to). Just one thing; you need to align it really good or else it vibrates alot when you lift the throtlle.
