Pretty much the way to go, I think the sound will definetly change and get more aggressive.

Im thinking about doing my own experiment on the stock oem muffler since its sitting in my garage overhead, I want to see If I can somehow get inside it by cutting it and taking out the packing material and rewelding everything and see what kind of sound that makes. I get pretty crazy when Im bored at home lol just start chopping shit up to see how it works.
