magna flow 4" on 6.0 sound question

[cj036.0]

this may be a stupid question but i just put a new magna flow 4" system on my 2003 6.0 and when it idleing or at a stop light the exhaust at the exit sounds like a hissing noise. Is that the way it is supposed to sound? Is that the turbo noise? Is there something wrong? I checked for exhaust leaks but found none.

Doesn't sound like anything to worry about to me, i have that too, it's just how the 6.0 sounds

Yeah it does sound really good. It seems like the wistle gets louder everyday as the muffler breaks in. Thanks for the info on the sound. I'm new to the diesel world and I'm luvin it.
