turbo/muffler question

["Louis A. Mulieri" <lmulieri@zoo.uvm.edu>]

      My mechanic advises me that I have a small hole in the rear muffler 
of my 5000tq.  I rather like the low, throaty sound and have not been in 
any hurry to fix it, but I wonder will it have any deleterious effect on 
the turbo performance or life?  It is my understanding that any back 
pressure is deleterious and my linear thinking would lead me to conclude 
that I should take the sucker off but I am trying to limit my linear 
thinking and be open to more non-linear ideas, even those leading right 
up to chaos.
	Thank for any help.
