not loud enough for me so if the centre section with the resonator in was changed for a straight through one how much louder do you think the prodrive back box would be,was thinking of doing this before trying different back box

ive done the same on my 7, still quiet enough whilst taking your time, but loud when your foots flat down, a happy medium i think, i had a p1 with a full ss decat before, that was loud !
