The slip ons give you 2 pipes... but this chart:

Shows a lot of dips in the powerband. Wouldn't then be better to get a full exhaust with one pipe that has a powerband that is smoother like this:

My problem is with sound... I hear that with only one pipe, there is severe back pressure. With two pipes this isnt an issue. But I dont understand the concept of back pressure. Sure I like the smoother powerband, but the Busa has power in spades... I'm more after sound. So where should I put my money? Two pipes or one? I've heard the two brother pipes... they are deep and throaty... Makes your bike sound really mean. Please help!
