Yeah, they installed cats on this car about a month ago, and one of them popped after just a few weeks. They wouldn't replace the cat under warranty, because they said there was something wrong with the car that caused it. The car runs like a raped ape with no check engine lights or anything. When I got under there, I found out that they had only run the smog pump line to one cat instead of both. In addition to the crack in the pipe, I think we found out what was wrong with the car. They also insisted on removing the H crossover to make the cats fit, when there was clearly plenty of room up the pipe to fit them in.
The car has since passed GA emmission, so we went ahead and put in a BBK long tube and X-pipe combination. I have some old cats off a 93' Mustang. I'm just going to make my own H-pipe for that once a year event.
