@Spazz and @danoday...thanks again to you both for the compliments. Always glad to help when I can even if it's not always the news we like to hear. lol
That being said, I got to thinking more about these '09 Power Duals last night and as far as fitting on the bike, they will install on the '10 & newer touring models, however, it is the size / location of the Oxygen Sensors that is different. The '09 & older models use 18mm ports near the exhaust ports on the engine while the '10 & newer touring models use 12mm ports near the transfer case to get the air:fuel ratio reading. Because of this, if you were to go with a fuel tuner that required the use of the 18mm O2 ports (ie: ThunderMax) then you could run the '09 Power Duals on your '14 Street Glide BUT if you were to run a fuel tuner that utilized the factory installed 12mm ports near the transfer case, you'd want to go with a set of Power Duals designed for '10 & newer baggers.
Anyway, just some "food for thought" on this fine Wednesday morning!
