B20db7: What kind of noise are you hearing? Rattles? What other kind of mods do you have? I highly doubt that our situation is the same. The rattles I'm experiencing are obvious and originates from the muffler. And when I say that my exhaust is loud, I'm talkin' almost 3x's than normal!

You said that you suspect "noise" coming from around the mid-section. Check that the heat shields are torqued down and not touching any of the pipes. Bend the shields away from the pipes if they're too close. The exhaust might shift slightly when you're driving and be close enough to touch and cause a rattle. I've done this in the past when I heard a slight rattling sound around the mid-section of the exhuast. Still, turned out to be a small joint crack between the b-pipes and resonator.

That's about all the suggestions I can give you with the info I have. Hope they help.
