There are different things that you can do to change how your powerband is going to be. If you make a muffler a certain way, youll have to make the piping a certain way (how you want the powerband). So, if you go with large 3" piping, you are already going to lose a lot of exhaust velocity. You need to make the muffler work for that size piping. I would say 90% of the exhaust brands out there dont know how to design "working" exhaust systems. Its all hype and branding really.
