Was reading my Service Manual about the stock exhaust on my new StreetGlide and came upon this

ACTIVE EXHAUST (HDI)

What is it and does my bike have it? Just says "on HDI models".
Is the 2010 StreetGlide a "HDI model"?

 

The "I" designates non-US models, I is for International.

 

Thanks! Bought mine in New Mexico but most people dont realize New Mexico is in the US! LOL!

 

i think it means the exhaust has a catalytic converter in it

 

No cat, it's a Euro sound thing, they have them on Porsches and others to keep the sound down in towns , so when you are part throttle it kinda keeps things quiet but when the exhaust pressure gets higher( don't know the specifics of how much pressure) it starts to open up and let the pressure out. There is a valve and another route through the muffler that it uses when in open mode.
