My 09 1300 has a Cobra slip on and NO controller. Don't know if it has been reflashed or not, it was on when I bought the bike. I doubt very much it has been reflashed because it does have some popping on decell. Other than that the bike runs very strong, and I think it sounds great. If you want the most you can get out of the bike, then a reflash or controller may be in order however.
2009 V Star 1300, with 11,000 miles. Solo bike with a Med shield and Cobra slip on exhaust.
