I've got a pair of direct replacement Dynomax Super Turbo Mufflers for MN12's. I just bought them from Summit, but decided to go with Magnaflows instead. So they are brand new. I was going to just return them, but figured if someone here was interested and wanted to pick them up in Iowa, I'd just sell them so I wouldn't have to bother with returning them and such. $150 at CC.
