Thanks Dave.
I am going to check with H-D to see if the XIED's are known by them or how it works with my warranty.
I have noticed in the past that many dealers do not know of many aftermarket products or their successes.
I have finally decided on
my exhaust/intake combination!

V & H Twin Slash 3" slip-ons (in black) with quiet baffles, stage I inake and the XIED (or variation) recommended by Nightrider.
Edit: I feel I should do the Stage I in addition as I will gain the extra rev to 6200.
H-D does not need to know anyway as the plug-in can be added or removed in minutes. No harm no foul.
So exhaust, intake, re-map, bring it home & plug in the XIED.
Bida bang
Just talked to Steve at Nightrider. Good guy.
