High EGT's

I have an early 99 F-350. The EGT's are running higher than they used to with no modifications being done to the truck. I checked to make sure my boot connections are tight but haven't had time to do a pressure test yet. I'm going to verify the EBPV isn't stuck in a slightly closed position (hopefully tonight). If the leak test turns out good and the EBPV is not stuck closed, I was thinking about purchasing a cat delete pipe for testing to see if the cat is causing a restriction. Does anyone have a suggested place to buy a cat delete pipe? Do the experts out there think I'm on the right track? Any additional suggestions would be appreciated.

Just to clarify on your last post...You got 200 less EGT with the new muffler or with no muffler at all?
I asked the same question a while back about running without a muffler. Here's the post and the answers I recieved.
Yeah, liked to know what you come up for readings with the new muffler in comparison to going straight pipe.
Cool (no pun intended). That's what I was hoping to hear. Sounds like a muffler replacement would be in order for any of our trucks then to get the EGTs down.
I remember a book a while back called "101 Uses For A Dead Cat"
