2.25/3" test pipes?

In my opinion, the 2-bolt gasket is going to be a problem now or later.

As Bigsyke said, you need to hit up FRsport/Courtesy/WestCovina/Performance for the OEM gasket, or get a aftermarket 3" gasket to keep your current system from leaking.

But really, all 2 bolt gaskets leak when you're talking about 3" stuff - Nissan's got to be the only company using big 2bolt gaskets - everyone else uses 3bolt... that's why when I had my system custom made (at a local well known exhaust shop), we used all 3bolt gaskets - and guess what? They don't leak, even after some track days/lots of mileage.
