Default whistle from exhaust

Ive noticed a new whistle that seems to be exhaust related-- increases with revs reguardless of acceleration. I tried to find it but couldnt hear it from outside the car. I hear it inside. Other than checking connections between pieces, is there somthing i can do to pinpoint it? The sound is similar to a climate control fan gone bad (the whine). TIA

it's not coming from the stereo speakers is it?
the post title reminds me of that old prank of putting a whistle in the tailpipe of a car. :crazy: :lol:

When my stock cats got clogged, it sounded as if I had a turbocharger under the hood.

Thats what it reminded me of is the tailpipe whistle thing. They dont make one to go over the PEs though so it has to be somthing else. It didnt do it yesterday afternoon or today.

Noticed in your sig that your cat is gutted. Guess it ain't your cats. The precats and the main cat are all three gutted? (I think the 87s had both, someone will chime in if I'm wrong)
