Anyone else use 2 gaskets for joining up pipe to gt spec headers.?? Ive fitted just one and it leaks then I noticed this on their website, I've copied this from their website...... GTSPEC Gen II exhaust manifold gasket set. Set includes 1 x uppipe to turbo gasket, 1 x downpipe to turbo gasket, 2 x block to manifold gaskets, and 2 x manifold to uppipe 3 bolt gasket. This set is part of GTS-PER-1016 (Gen II manifold for EJ207/EJ257 Subaru Engine). We suggest to use two 3 bolt gaskets on our header system for the best seal.

Well I used one on my equil length length headers and now I have leaks at the turbo/down pipe because I think the down pipe sits in a slightly different place so maybe another gasket would solve my problem. I think with any aftermarket part there is a certain amount of "fit it & fettle it".
