The Borla-exhaust discussion flares up here every few months.  Seems
most everyone likes the performance, sound, and durability of the
Borla, but installation difficulties crop up regularly, including:

	- Pipe comes too near or contacts the differential
	- Pipe has no heat shield near the differential
	- Catalytic converter bolts shear off
	- Muffler hangers cause incorrect orientation of tailpipe in
	  bumper cutout

I want to install the Borla exhaust, but every time I look under the
car I don't see how anyone could improve much on Mazda's
original-equipment pipe between the cat and the muffler.  It has good
clearance, and heat shielding to boot.  Many of the installation
problems seem to crop up in replacing this pipe.

Do you have experience with the Borla?  Can you advise if it is
possible to connect the Borla muffler to the stock pipe?  Is the
allignment of the tubing close enough?  Is the Borla pipe diameter
close enough?  How would you do it?
