on the 1999-2001 donor LS truck engines it is a common mod to delete the EGR valve and block off the opening on the passenger side stock exhaust manifold like so, though I prefer to go to the junkyard and just buy a stock factory exhaust manifold off of a 2002 or newer vehicle which already does not have this ugly appendage.
