Okay everyone, I have the hotbodies exhaust. I am taking it off and putting an Arata or Tiforce high mount on it. I recall taking off some box thingy as well when I installed the hotbodies exhaust. Is anyone familiar with what I am talking about. I want to get my low end and midrange up more. Do I need to put that back on as well? What is the purpose of it? Will it be a factor in getting more low end and midrange?
