Hi Jeff;
The hole is a "weep" hole, which is there purposely to
allow condensed water to drain out of the muffler, which
results in less corrosion, and longer life for the muffler.
I think the OEM Dakota mufflers have a stainless steel
outer jacket, but chances are, the internal baffles, etc.
are not stainless, and will rust, thus the hole.
Mine is coming off pretty soon too...I'm still shopping for
the best pricing on a Gibson cat-back (single 3") at the moment tho'.
