You'll definitely need a Power Commander or something similar. I don't believe that the gen 2 can be flashed or will see any benefits to a flash-but don't take my word for it. I don't recall 100% on that one.
If you haven't done it already, I'd very highly recommend doing something about the front brakes. Oh, and get the suspension sorted out if you haven't been down that road as well.
Just to satisfy my curiosity, did you buy the Arrow new? I always liked the look of Arrow. If so, where from? I didn't think there were exhausts still available. I've got a LV on my 2nd gen and it looks great but the stock system is more appropriate for my needs. One of these days I'll buy a new exhaust servo and slap the OEM stuff back on.
