you are called motorsport and you don't know the effect removing a kat? strange :D
when you remove a kat you'll see a little torque lose at low rpm expecially in little engine and expecially in n/a engine. There's also a little power gain in high end rpm
to the contrary usually you'll see a torque gain on big engine, expecially if it's turbocharged due to better exhaust flow

you loose torque because you have less inverse pressure!
you need to remap your ecu if you want to feel something different!
