What do you guys think, I seen a picture of a set of GT take off mufflers, a left and a right on ebay from mike casco for 45 dollars. I want just a right but seeing it is such a good deal I will take the lft one off his hands and maybe someday I will convert to duals. received his package in two days I thought great, I told my son ,get the ramps, lets get this muffler on!(first mod ) I open the box and there is 2 left GT mufflers?what the ^%$#. Did I get took or do you think there was a mistake. I emailed him ,no answer yet, and calling does not do any good. If I was took What can I do if anything.?
