I say exhaust leak because it seems like there are those chappy flanges on the end of the parts...maybe it could be it. If this is the case, should O just buy my own flange and replace them? (maybe a v-band clamp?)
Sorry for the long post with multiple questions, I just want to find someone who has had experience with this type of problem before I take the plunge.

Well I don't think it's so much a rumor as it is an aspect of our VQ engines. I get the hissing when I let off the gas and the engine is in gear and starts to decellerate. The sound doesn't bother me though, I'm not sure if anything can be done to make that sound quieter if that's what you're looking for, short of keeping stock cats on.
BTW: The sound is not present while accellerating at all.
