Installed test pipes ~2 weeks ago, and used Z1's multi-layer metal gaskets. Frustratingly, the seal of this product was extremely lousy and there was a visible gap between the gasket and flange (neither flange is warped).

I ordered a set of Fast Intentions gaskets to remedy the issue, but while the design looks great I'm still somewhat worried they are too thin and I should order a second set to double-gasket the flanges. Has anyone done this before?
