leaky up pipes?

i was driving to work this morning and after a long pull the truck started to make a god awful screeching sound, only when on the throttle, stopped and check my intecooler boots and they looked ok, sounded like it was coming from the turbo, i carried on cause it seemed to dive ok, noise continued, slowly started to make less boost at part throttle, i think maybe the up pipe is cracked where the flex section is. kinda tuff to see, smells like exhaust under the truck, does any one make an upgrade for these?

Check your boots again, take them off and look.
Mine had some hairline cracks in them that I only saw when I had them off and looked closely.
But it might be the y-pipe, look under the truck for black on the firewall.
If it is the y-pipe you will need to pull the turbo to change it.
Elite Diesel has a nice upgraded one that I just put in if you need one.

Also check your exhaust manifold bolts, they might have worked loose.

When my y pipe was bad, it would make a hissing sound that would come and go at idle as the turbo cycled. Also would get a cloud of smoke come from under the hood when I goosed the throttle. (with a smokey tune) and soot on the firewall.

If you mean the cold side of the CAC I would think you best bet would be the dealer.
