I had my 2016 ST (with 5,600 miles) re-flashed by Anthony recently. It was all that everyone said it would be -- great, and I really love the bike now. That was the best bang for the buck I have ever gotten for one of my motorcycles. When I had Anthony do the re-flash, I told him that I had purchased (but not installed) a full Arrow header and exhaust system. I asked him to do the re-flash in such a way that it worked with the Arrow system. Later, I asked him if his re-flash would work with the Arrow exhaust system once I had the exhaust system installed. He said that, typically, the Gen 2 STs work well with the Arrow system. My question is this: Does anyone have experience with (or advice regarding) an Anthony re-flash and a full Arrow system but NO other modifications? In other words, what can I expect when I put on the full Arrow system on top of the Anthony re-flash? Will it work well? I would obviously like a power increase and better sound from the Arrow system, but am hoping that it does not negate all the "rideability" benefits achieved with the Anthony re-flash, or require a second re-flash. Also, will this combination require me to add a Power Commander V or other product to make the re-flash work with the full Arrow system? Any advice would be appreciated.
