I was wondering if the Screamin' Eagle® Nightstick 2-Into-1 Slip-On Muffler would be considered a "free flowing" muffler. I was thinking of going with the K&N air filter and a TFI Gen 3 on my 2010 FLHX. She has the aforementioned Nightstick installed already. Will I need to make any changes to the exhaust when I install the Gen 3 ?
 
Are you just using a K&N air filter or a full stage 1 air cleaner. Would advise complete air filter upgrade. After setting TFI to spec you are good to go.....
Exhaust will need no additional set up.
