However, I'm sure he could have installed them without any issues. They would have slipped on and clamped just as well as the pipes he used, right?
My headers did not have a long straight section at the end (maybe 1" or so?), but it didn't seem to be a problem for him to connect the pipes and clamp them. I haven't seen any evidence of leaks (and I've looked for them).

what cats should i buy to fit the OBX headers into the 2.5 inch Corsa? They have to get rid of gas smell; (at least somewhat) that's what catalytic converters do, they burn the excess gas off
