First day on the S-197 forum. I recently purchased a 2008 DHG Bullitt #2957 with 13,000 miles. Previously owned a 1998 Mustang GT. Retired, but still want to have some enjoyment with my Bullitt. Just swapped out the stock Bullitt mufflers to FR500S KR's. Very pleased with the swap. nice throaty sound. Otherwise stock. Of course, my damn Shaker 1000 cd player won't work. Seems like a common problem. Tried many of the suggested quick fixes but no luck! I'm researching future upgrades, just have to see how my Social Security budget hold up!
