Its for ae86. The question is where do you get the t3 test pope gasket would any local exhaust sells them or any suggestion.

Thanks

It's a standard 2 bolt flat flange gasket. They can generally be found at tuner shops. However, the t3 unit is 2" ID which is smaller than most other applications and will be more difficult to find locally, but they're easy to find online. I recommend a copper or graphite gasket. The commonly available metal/paper gaskets work, but they suck.
