dual question
ok, you know how the kazuma is such a good HP exhaust because it lets the exhaust gas flow so good right, well isnt that reducing backpressure just as much as a dual exhaust??? i dont get y a super unrestrictive single exhaust is better than a normal dual (besides the weight)
can someone who knows about this stuff anser this

kazuma is strait through...therefore easier exahaust outlet but less backpressure. kazuma and dual will give you less torque as a result of less backpressure. the dual will give you less horsepower because it is more restrictive.

why does less backpressure make less torque?

It's not backpressure, it's velocity (speed). You must maintain the speed of the exhaust gasses or else you lose torque. Duals (or a single pipe that's too big) allow the gasses to slow down on thier way out, causing you to lose torque. With an exhaust you want to move the highest amount of air possible (usually by removing restrictive mufflers and bends) without allowing the moving gasses to slow down.
