Frustratingly, removing your catalytic converter has a very tiny effect on performance, and an enormous effect on emissions. Kids into car culture tend to hold very superstitious ideas about cars and performance. (eg, the manufacturer intentionally hobbled your car with a restrictive cat-back exhaust, and replacing it with something loud and terrible will "unlock" a significant amount of hidden horsepower.)

The reason for the superstition is that it is true ...in the 70s when the latest in emission technologies was clogging the exhaust with platinum balls. Now-a-days converters are built intelligently & removing it just reduces performance by fucking up the O2 sensor readings unless you also dump a grand on a new ECU

You can also get a piggy-back ECU for the purpose of sending false sensor data - it's quite a bit cheaper.
