Default Quick exhaust question

I have a 350 tbi with crane cams and some other mods, with slp shorties and flowmaster thunder catback, I've been getting an awefull high pitched tin sound when I rev above like 3 grand along with the beautiful rumble, its worse when the engine is cold and seems to go away after ~10 min. It didnt do it near as much when I bought it about 2 months ago, it really seemed to start when my friend adjusted my TPS.. Any ideas? The sound drives me nuts.thanks-darren

Naa its deft. in the exhaust, you cant hear a thing around the engine, or even mid car, but once you go back by the tips it just sounds bad. It dosnt sound mechanical, just tinny. I heard it in a diffrent camaro the other day(v6) and tons of piped out ricers all the time, -darren

It could be an internal problem that makes it's way out the back though.
