Spohn 503 subframe connector

Tried the search but didn't see what I was after. The 503 subframe connectors from Spohn say they fit dual and single Cat applications. I have a single CAT in the factory location. The picture on their website has the tie-bar going right through the location where the CAT would sit. Am I missing something? How did you guys find the fit on these things? I'm not seeing how that tie-bar will attach with the converter still installed.

It will go between the cat and the floorboard. It's tight, but it will fit.
