Adding a vance and hines high air flow filter and intake to my 2012 street glide. Will I need to do anything else to it or just install and ride?

 

If it's for looks, your fine. But to get any real performance you need it tuned somehow.

 

Strictly for looks.

 

If you've done anything else to the exhaust, like change out the stock mufflers, most likely you'll need to retune the air/fuel.

 

Ive changed the slip on mufflers.

 

Does the Bike still have a catalytic converter in the header pipe ?

If yes most likely you will need a Tuner of some type, minimum XiED , or Fl-ViED-10
from Nightrider. If no Cat in header pipe then full on tuner will be needed, maybe one
with an Auto Tune.

 

no converter

 

Will probably run hot and give a bit of decel pop. You won't hurt anything if you don't beat on it. Best thing to do is get a tuner and be done.

 

Agreed , good post.
