I posted this in the experiences forum but want people to see it here, thanks.

I've had my carsound cat on for less than 3 weeks and it's already busted. The honeycomb core came loose and is sliding back and forth while at a stop and accelerating. It's annoying as hell and I had to put my old busted cat back on. Worst thing is that warpspeed doesn't respond and they don't refund cat converters. Also they installed the O2 sensor hole on top instead of the bottom of the cat. Once again screw them...
