Gutting cats, good or bad???

Not to argue with Try Me, but you will see some HP increase but not much if your stock, maybe 5HP or so, I did have headers, and a Flowmaster(on my 90' L-98) as far as the exhaust goes, I did get a little more ET and MPH without the cats about a tenth and 1MPH in the 1/4 mile! but I doubt you will see that much without headers, and a free flowing muffler!
