03 Intake modification?

I have my intake off for various reasons, and while its off I was gonna have it hot tanked and was debating having the connector across the back removed.
My questions are... Is it worth it? Has anyone seen any performance gains from doing this? Is easier access to the HPOP the only reason for this? And if it is, I guess the EGR cooler can come out w/o removing the intake?? Because accessing the HPOP, from I can tell, can still only be done with the EGR cooler removed. (For reference, I have Bulletproof Diesel's EGR Delete). Thanks for the input.

It can be cut out with no issues down the road. Plenty of people have modded a 2003 manifold for use on the 2004-2007 trucks. I'd suggest getting a competent shop that knows how to weld aluminum. Additionally the heat from welding could cause the manifold to warp causing sealing issues so ensure it's bolted down as if it were installed when they do the work.

The 03 manifold can be a pain to work around but I like the fact that it balances the rear cylinders and help with slowing any warping that may occur.
