I don't care about using stock locations. I care about the fact that unless you used the exact same jig as a factory exhaust, any deviation from the OEM setup may be putting too much stress on the front pipe.
How is it bolted together? Is it using the stock donut gasket or a regular bolt/nut? How are your exhaust hangers? How much movement do you have? Did you have to have the custom exhaust at a certain angle to mount it?
A lot of people don't realize why welds on exhausts break in the first place. It's usually because the entire system will break at the weakest point, especially when non-OEM parts are used. The jig used to fab the exhaust is key... and it's also why cheap exhausts fail, because they just buy an existing exhaust and copy the flange/hanger locations instead of actual R&D on a physical car.

Edit: as for your front pipe problem, it may work fine. I'm just saying that your custom exhaust may be exposing the current weakest link in the system.
