Years ago the beads of brazing around one of the reference tubes on the EGR tube for my Lightning cracked, eventually the small tube broke off completely. My point... although its not common the EGR tube can fail.
EGR Delete Pros:
Cleaner engine bay (less clutter), easier spark plug changes
EGR Delete Cons:
Non-compliant for emissions testing
If you delete the EGR make sure you decide whether you will be deleting the EVAP system at the same time. I say this bacause you can delete the EGR, the EVAP, or both simultaneously. Most EGR delete "how-to" threads don't specify so there ends up being confusion, codes, etc.
One more point of consideration... it drives me crazy to see guys delete these systems but retain the factory vacuum lines with lines capped off, re-directed, etc. Doing this is unnecessary, confusing and leaves the system open to future vacuum leaks. IMHO do it right... take the time to pull the SC off, remove the factory vacuum lines, and spend $30 on vacuum line and various t-fittings and y-fittings. My $.02.
