On the topic, does anyone know the size of the 2 bolt flange on the front of the stock midpipe? I ordered a 3" DP with a 2 bolt flange specifically just to bolt to the stock exhaust for now but measuring it seems pretty big. It's actually 3" all the way.

I'll try searching for dimensions of a gasket or something but if someone had a stock midpipe laying around they could measure, i'd certainly appreciate it.

EDIT: this looks exactly like my DP so looks like i'm golden. https://www.clublexus.com/forums/7459102-post11.html

the 2 bolt flanges on those supra downpipes will bolt up to the stock 2 bolt midpipe flange, they are the same size as the ones they use on the downpipe. you can reuse a stock gasket or use an aftermarket one, surprisingly they are large enough, and also makes you wonder why they made the stock flange large enough to fit a 3" pipe easily inbetween the bolt holes when they used a 2.x size pipe factory.
