I'm also very upset over the smaller diam flares, and it's not for easy fitting into the h or x. It appears to be MUCH smaller diameter, maybe to make it easier to mate up against a stock mid-pipe. i have a 2.5 Bassani X, which only lines up without leaks if the passenger side hangs down low... which scrapes on my lowered card.
So i'm stuck ordering some real 2.5 flared tips from a bending shop and custom-welding them on. For a $300 exhaust setup this might be acceptable, but this cost 2x that. It should practically be installing itself.

getting 2.5 ends, hopefully they fit OVER the Borla ends and i can clamp them down without welding.
