Good call.  I killed the motor in the 92, due to a PP+ pipe ceramic cat that
broke apart (street driving, less than 25k).

The PP pipes use T304 stainless, .083" wall and 2.25" dia.  The SS pipes use
.065" wall IIRC, and are lighter.  I'd be interested in a light .065" wall
catless unit for my open track 89.  Stock OEM pipe routing (same as the old
PP+), the SS unit gets in the way of the oil drain plug.
