Make the intruder louder ! ! !

Hello together. My name is young hair. I’m new here and I have a question with which I don’t know any more. My father bought a 1400 intruder and doesn’t agree with the sound image. Can I make the production exhaust system louder? If so how? And would that be very loud from the loud strength? Have seen that in the bags ever 3 rivets. Is it enough to remove these and remove any insulating wool? And yes I know that’s not leal. Thanks already for coming E ideen. MfG young hair
