Goodwin Racing RS II Duals for 2006-2008 Miata's with the appearance package. You can read about it here.

It comes with two stock baffles and I also have the two extra glass packed baffles you can read about here.

This cost me just over $440 but I am asking $340 shipped in Texas or you can pick them up in Austin for $325.

This exhaust has between 600-800 miles on it.

The RS II Duals give you a bit more flexibility with the baffles as you can use none, one or both of the stock ones, or one or both of the glass packed baffles. The tips are double walled since they have to allow for the insertion of the baffles that screw in from the bottom. The RS II duals are about 7 pounds lighter than stock.

If you want to see pictures of them installed on my car, just let me know and I can e-mail them to you. Again, the RS II Duals that I have are specifically for cars with the appearance package.
