Pud,Monstro if I remember correctly said de-catting his 147GTA made a huge difference and de-catting was a lot better than hi flow cats.For 50 pounds you really have nothing to lose if the gain is insignificant and a lot to gain if it is.I would do it.Also I did not de-cat I just replaced the origional cats with high flow cats and that on its own transformed the car so I will be surprised if you don't get a big gain,but I am no expert so maybe I am wrong.
