Hey guys just installed some kleemann headers and I notice a hissing sound when I accelerate like air leak ?could it be a leak or since it passing more air threw thats why it sounds like that ? When I rev it cant hear it or when car is idling. thanks

I would check for cracks at the weld. I think they are of "not so good" quality, the current cheap ones.
They were better when they were made by a german company for Kleemann years ago.

Especially with stock mufflers, you can hear the exhaust gasses passing through the primaries at lower RPMs. Could be described as a "hiss". Stock manifolds insulate this sound. If they were loose they would tick when cold.

Never had a problem I've had two sets of Kleemann headers, just doublecheck all your work and make sure everything is sealed up and tight.
