Cat delete HP gain

[NDW]

Have any of you done a cat delete on your car and know if there were any hp/torque gains? I have the 3" corsa exhaust and the roe oval hf cats with the 2.5" inlet/outlet. It is my thinking that the restriction down to 2.5" might be deleted for a little extra hp. Thanks.

I am not an expert on this but from what I reading the gain from high flow cats to no cats was minimal (under 10hp) at best. Plus, you have to deal with potential emission issues, odor, and fooling your PCM with simulators.
