I also had problems fitting the Liestritz (Millen) muffler.  It, too, did not
ride centered in the exhaust cut-out in the rear bumper.  I fixed it by having
a muffler shop put a torch to the exhaust pipe near the diff and bend it to
place the tip in the center of the opening.  Other than that and a tendency to
leak at the muffler's connection to the exhaust pipe, I really like the unit. 
It sounds great and the big glossy-black-enamel, oval tip looks cool!
The leak is due to the slits in the muffler's pipe.  They accomodate sliding
over the upstream pipe.  Unfortunately, one of the slits is at 6 o'clock and
doesn't close tight enough under the clamp.  This allows some exhaust
condensation to dribble out at that point.  I did a shade-tree fix by puttying
up the hole with epoxy.  It stopped the leak, but I suspect I'll become
familiar with the intersection again in the future!
