Jay, there is NO advantage to removing the cat, no performance gain at all. The fjr uses a honey-comb brick style cat that only restricts exhaust by the pipe size, nothing to gain by removing it and may actually kill your fuel economy.
I used to drag race my 94 dodge Dakota and was always looking to gain more power and all the internet experts claimed at least a 25hp gain by removing the cat so I did and found nothing, zilch, nada. The only thing I gained was a 4mpg loss of fuel eeconomy and a louder exhaust.
So I called the guy’s at More-flow who specialize in high performance cats and talking to the owner he started laughing at me as I told him my sad story, he said that that removing the cat performance gains was pure Internet myth and that pipe diameter affected things more than the cat did. So I would recommend not removing it since there’s nothing to be gained, which is the case with most modern emissions these days.
