graydon proline exhaust

[250xrider909]

Is the graydon prolin exhaust louder than most other pipes out there and will it really help my 250x??????????

on the 400ex, it is actually quieter than what i am use too. also, it will give you a gain but it doesn't seem like any of the honda's really open up after adding a pipe. for example, it won't be from a regular bike to arm jerking power
