What all did you have to "modify" to get them to fit with the NPP exhaust? Just grind a little off the end?

Thank you!
And there was a little nut that that I grinded off.
It was on the factory exhaust pipe and it initially was used as a little clip to hold the bracket that mated the factory cats to the exhaust.
I put a big circle of the location of where they bolt together, and I put a little red circle where the nut was that got grinded off.
So I grinded it off, as well as did a little grinding off the edge of the exhaust pipe to squeeze the high flow cat in between the collection pipe of the header and the factory NPP exhaust.
