Can somebody let me know if this looks right? I thought the donut was supposed to crush all the way down. This is the flange between the new CAT and intermediate pipe. Will this leak or is it OK?

 

Looks good to me.

I know on some years there is a different size front and back.

You should be fine I always use prematex form a gasket #2 on all my exhaust gaskets it helps seal and holds them in place putting it together.

 

Thanks wyoming. Yeah this Cat is smaller in the back and bigger in the front, 2 different size donut gaskets. I always thought that the donuts were supposed to crush all the way down and the flanges were supposed to meet but it doesn't seem to be working that way here. It looks like it's crushed enough to seal, just always thought it was supposed to crush completely down.

I'll give it a shot and see how it goes.
