Brera 2.4 Remove Precat

Hello everyone,
I just got a chance to buy a downpipe that removes the precat in the 2.4 159/Brera engine, but i'm unsure if I should do it.
I already have the DPF removed and the car is remaped. Are there any further gains to be had by removing the precat? What about the noise, will it change? According to eper the original pipe is a silenced cat.

Thanks!

You'll get more mid range percieved torque and teh turbo will spool quicked so better throttle response.
