holes on bottom of stock coupe mullfer suppose to be there?

[infinkc]

i pulled off my stock muffler because it had a big hole on the bottom,
i noticed there are 3 1/4" holes drilled on the bottom also evenly
spaced along the bottom, one in the middle and the other 2 on the sides
about 1 inch in, i was wondering if this is normal? it looks like it
was there all along, they are not rust holes. I purchaase a used
muffler but it still hasnt came(been almost a month since the person i
bought it from got my check), and i dont think it will, so im back to
repairing my stock one.

So who is the guy that has not sent the part, we would all like to make him
feel the value of his mistake.

As to the holes in the bottom of the muffler. I drill a single hole in the
bottom back just above the lip. Because, for every gallon of fuel your car
burns, you make a gallon of water. And if you don't drain it out it will
rust out. The water will find a path to the outside of your muffler one way
or another. And, years back, mufflers came with a drain hole. EPA took
them out. So drill a small hole in your muffler and it will last twice as
long, maybe a lot longer.
