I had a bulletproof egr cooler installed on an 03 6.0 and I believe it's leaking exhaust from the clamp where it meets the Y pipe. Does that sound legit and if so is there something to seal it with, do I need a new clamp or is it possibly something else altogether? It got studs and an oil cooler at the same time. It has nearly no boost till about 2800 rpm or so and I can hear the pressure leak from the cabin. I'm fairly certain I've felt the leak and was hoping for help before I take the truck out of service an rip the turbo piping apart. Thanks.
