It does not. Softails that had them used thermal reactors in the mufflers but that was only in 2006 (CA) but not 2007-2008 because they went to closed loop. They weren't used in anything in 2004. Op leave your bike alone and ride it.

 

OP and his bike are in Florida. I am in Michigan. I have never seen the OP's bike. I can't say with 100% certainty what it has or doesn't have. I know that my '04 Road King didn't come with a catalytic converter.

 

Everyone keeps referring to the "right muffler". Since the stock exhaust on a Fatboy has both mufflers on the right side, which is the right one? Top, bottom, front or rear?

I am pretty sure that you do not have catalytic converters in your 2004 Fatboy.

 

I stand corrected. CA Softails had converters in the mufflers starting in 2000. If the OP's bike does not have CA emissions it does not have converters.

 

Unfortunately, I live in the Peoples Republic of Kalifornia. I bought an 07 SoftailCustom new from a dealer in Fullerton. I put Rush slipons and when I looked at the stock mufflers, I did not see anything that looked like a converter.

 

Your 07 Softail did not have converters. It was the first year of O2 sensors and they were able to get away without using them in 07/08 on Softails.

 

Thanks for pointing that out

 

I have aftermarket pipes. Here is a pic. Any thoughts on a possible cat inside? Thanks
Is there a 'catalytic converter' in these pipes?

 

I will guarantee that the right hand 07 stock muffler had a catalytic converter in it, and the left hand side was nearly hollow except for a long tube with a bunch of holes in it. I still have my 07 mufflers and they sucked, and I hated them with a passion. I also have a pair of later 88 Ci mufflers and they are both the same, but they don't let enough exhaust out of a 103 engine, so they suck as well as the 07s. The 2010 and up mufflers are the ticket and I like the snot out of my 2015 mufflers, no catalytic converters, and they are as fine as frog hair.
