Personally, I think any exhaust whether it be muffled or straight piped would have to be pretty darn loud to drown put the loudness from having the 6637 anyway,just my .02 worth. I actually have a 4" Turbo back Magnaflow with the muffler delete pipe and its not that loud inside,I get more drone(so to speak)from the intake(6637).

Good point about the WW Kevin,I have the WW/ATS Housing set up with the 6637 intake and in most cases I cant hear my exhaust at all.

Why do you have the WW *and* the ATS? I have the stock wheel in my ATS, and get 30psi out of it (van turbo). Zero surge, and enough whistle, but not obnoxious.

So I was wondering why its twisting in there? Does that help with flow?

The one i had on there was a piece of garbage and my buddy had a wrecked f-350 at his shop with the 4 in. Magnaflow on it so he gave is to me so i swapped that on my truck. Just never changed my sig. See i would love to do just the straight pipe, especially since you say it sounds good with that exhaust, just the inspection is what's killing me!
