headers and squeal

I am about to buy pacesetter LT's and there off road y. Do you guys have good luck with the clamps sealing? Also when my truck is at wot and goes to shift it makes squealing noise from the front of the motor. My shift rpm is 5800. It sounds like a belt squeal or maybe my intake sucking air? idk. has anyone ever had this problem? I have an afe stage 2 cold air. any help would be great thanks

Sounds like a belt squeak possibly. It could be the tensioner not strong enough anymore or the belt might just be old and hard.

Yea thats What i was thinking. Could It be the ac or proley the main belt?

Probably the main belt or tensioner/idler pulley, but do not count out the A/C belt.
