These mufflers have some surface rust on the outside as seen in the pictures and they do have some rust inside as well. They still have the clamps on them however can be easily cut off. They still sounded terrific and would still make an excellent pair of mufflers. 2.5" center inlet, balance out outlet. Retail for around $90 each.
