Hi, I'm shopping around for a stock muffler for my 93. Can someone help confirm the number? So far I found 18310-MV9-631 and 18310-MV9-930. Also, was the stock muffler black or bare? Thanks.

 

There are actually more part numbers than those two, according to the parts fiches, but they are all priced the same, and I'm not certain what the differences are.
The stock color is black, and mine is for sale - PM me if you're interested.
