You might actually lose horsepower, the system is designed for a certain amount of back pressure. In general, there's no benefit at all to going catless, and if you do you have to deal with the smell. Also, there's a reason that cars have catalytic converters, the level of pollution is a huge amount lower than when they didn't have them.
