420a stock cat question

[j5productions]

Hey y'all i searched and couldn't find a good answer.
What are the flange sizes on the Stock cat on a98 420a eclipse.
Im getting a new downpipe because mine is going bad and i need to know whether its a 2.25, 2.50 or a 2.00 or possibly even different. Any idea?
Thanks guys

The inside diameter is 2 1/2 inch just make sure you get a n/a downpipe. I got an obx downpipe and they sent me a turbo one which the flange is 45 degrees off and had to use exhaust clamps to bolt it up.

So is the flanges 2.00 or 2.25 or 2.50 on the stock cat flanges? I just don't wanna get the wrong size header/ downpipe.
