wondering who has these and if they like them? Also if you have noticed any power loss at low rpms after installing them

 

Went from a 2<1 FM Road&Track to the fuelmoto ss headpipe with GNX mufflers on my 18 FLHTK with a 22x cam. They are very high quality and I personally love the sound. Following the advice of FM, I left the muffler inserts installed and had no noticable loss of torque. If anything, low end torque felt slightly better.

 

Have 'em and love 'em.
Over 12k miles on my 19 limited with them.
Sound good when you're on them, not droning obnoxious on long freeway runs.
Outstanding quality and workmanship.

Can't wait to see how they sound next year with a Woods cam and PV with Dyno tune from Fuel Moto.
I do not run the inserts in mine.

I ran stock mufflers the first 6-700 miles I owned the bike. No noticeable seat of the pants performance decrease or increase.
I just wanted more sound than stock and they fit the bill. Very happy with mine.

 

I'm running them on mine with the inserts removed (stock header). Couldn't be happier with the sound, fit and finish.
