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 ?
