Car is off the road at the moment as it has a few problems one of which is a blown exhaust manifold to turbo gasket. While replacing this I am going to replace the head to manifold gasket and have been looking at multi layered gaskets. Will there be any real advantage getting a seven layered one over a three layered one? Performance wise I am only looking to get it up to around 320 bhp (well I say that now).I've also decieded to get a stainless elbow and down pipe and am getting one made up by AM Performance. Do the standard gaskets fit this system? And if so does anyone know where I can get them for a reasonable price?
Just buy the S15 3 layer metal gasket.
There will be no benefit at all of of the other ones you mention. The only real benefit of the S15 gasket over the stock GTiR gasket is that the S15 gasket fits properly and doesn't partially restrict the ports, like the OE one does !
The AM Performance exhaust should come with a gasket but, the stock turbo elbow gasket will fit the AM elbow.
With regards to the AM Performance pipes, I'd read through the various threads on here before you give them any money. They seem to be all over the place where fit is concerned and it looks like an accurate jig wasn't created when the prototype pipes were made up !
