That's what I thought too until I ran the stock cats after the fact without any problems / leaks whatsoever.

However, thinking about it, it would be pretty hard to bend the flange if you're using just a socket wrench and not an air impact wrench. Plus it wasn't gorilla torqued whatsoever.

I've done it before with a wrench and socket. Only way to check is to check.
