Hissing sound with akra evo

Hey guys,
I tried searching but only found one other thread mentioning this issue but no real answer.
I just had my akra slipon upgraded to the full evo with the akra front pipes, and have noticed this Hissing sound coming from the rear around 3-4krpm.
Has anyone else with this exhaust noticed this distinct sound or is this an abnormal sound ie: leak?
