Non CA 14 Models Cat Converters?
Do all 14 models have catalytic converters or is it still only California bikes? If other states don't have them how are their bikes tuned stock from the factory? I keep seeing posts that say if you remove your Cat you need a tuner but bikes in the other 49 states have come stock without them for years.

all since 2010. ( Class III, Tier 2 applies to all 280cc+ models)
the ECM should be able to compensate for the lack of a cat in the exhaust tract- and the greater flow potential.
However with the stock restrictive 2013 and earlier air cleaner the potential won't be realised due to restriction.
the 2014 model has a higher flow intake- I have not yet seen flow numbers, but HD says 15% more- so about 175 CFM ( compare to about 250 for the S/E and the Ness BS)
with a high flow exhaust, a high(er) flow intake and resulting high flow through the motor will probably require tuning compensation
the 09 models came without cat for 49 state markets and with for CA and export - and some CA spec bikes are carried by dealers outside of CA ( like bordering dealers so they don't stock 2 versions of each bike... ex Yuma, AZ)- the VIN will tell which build version a bike is.
