Theoretically yes as you'd still be stopping the exhaust gases been recirculated back into the intake system. The delete pipes do away with the EGR valve completely and not only flow better you get rid of the poxy bayonet hose connection which always leak. On the downside you also remove the ASV (anti-shudder valve) so engine shut down won't be quite as smooth.
Personally I'm still in two minds about losing the ASV as its also there as a safeguard against engine run on and a certain self destruction...
