If you cut the cats off of it , in texas you will have to get it inspected eventually and it will fail. Don't screw it up by cutting the cats off.
Essentially an off road h or x pipe is for track only use and it is not emissions friendly because it has no cats. There are other factors as well since most after market o/r pipes are designed much better than the stock ones.
I would not consider a stock pipe with the cats missing an off road pipe, I would consider it a hack job. This is what it looks like when someone tries to cut out the cats and piece together the mid pipe . I bought my car like this and immediately replaced it all with a aftermarket x pipe and new down tubes.
