Yes that right. Want to change my flhx 2011 header. Instead of removing

the cat, thinking of using an other header from an other year bike thats

fit.even putting the senors back on the pipes.....sooo,, which flhx headers

from what year can i use ..and will i be able to use my sensors...

Bye bye heat..and a bit more sound... Thanks again..

 

headers from different years without cats use different size O2 sensors and will not fit your O2 sensors.

 

CA bikes have cats from 09, 49 state 2010

different size o2 sensors if you get an 09 header...

nightrider.com sells bung adapters or you can take the new header to a muffler shop and they can weld in...

or

easiest way, all around- remove your cat from your header.
You aready own it, and any other way is going to cost you one way or another

A bunch of us just bought the header from American Custom and be done with it. Most of us kept the stock header, w/ 130 credit and take away 25-30 to get it back, not worth 100 bucks. Might use it later!
I love less heat and neat sound w/SE ac and DL.
Only way to go, IMHO
