Up for sale is a set of FlowMaster "HushPower" mufflers for the 05-10 S197s. These were used for about 500 miles before coming off 2 weeks ago. They sounded great on my car with ARH Longtubes with uncatted X pipe, nice deep tone. 4" round tips are in great shape and shine great with some mothers aluminum polish. These retail for about 430.00, im asking 300 plus shipping.
