Weird Groove on Converter snout/bad leak

my converter is getting dropped off at a place that builds custom converters tomorrow hopefully. Guy there said there is a good chance that my snout isn't welded straight on my current one. I kinda hope thats the case so i dont have to worry anymore. I may end up having him build me a custom converter, they are very reputable and build some bada$$ stuff. Im probably looking in the mid $600 range, but it will be strong and hopefully get the most out of my motor.
