The difference is in the header pipe.  The pictures I posted in the other thread make it perfectly clear why some can't do it without that angled adapter.  Simply stated, some header pipes aren't straight enough.  

I'm not sure why anyone would take that as a personal insult or an invitation for an argument, especially when other forum members have already admitted using an angle adapter and even posted pictures and directions on how to make one.

Siriusjoe, I doubt anyone would take that as an insult.  The only friction in this thread may have to do with the people who have never attempted this conversion and therefore cannot speak with any authority about it, but insist on arguing anyway.  As for the header pipe, the problem most people have had is not the angle of the pipe, but their inability to get it far enough in the muffler.  In about the 2 years I've been on this site, your complaint about pipe angle is rare.  Most people have adapters made because they have difficulty sliding the header far enough into the muffler, so instead they use an adapter to make it easier.

RTC, my error and I stand corrected. I  changed my parts number posting found earlier in this thread, and will accordingly advise anyone in the future who wants to do this conversion.

About the CAT, Serowbot said:

"Harley 65844-95 is a rail mount w/ internal cat. from a FXST 1450cc Softail"

If Serowbot says it does, you can believe him.  He has considerable experience with these conversions.

RTC,.. if it has a cat,... it will be clearly printed on the side with the EPA certification...
Looking in from the intake end, it looks like a coiled up hacksaw blade... it's basically nothing more than a heat coil, designed to burn up excess pollutants...
Negatives are the extra heat, but insulating exterior metal is designed for it, so external metal temps are said to be no more...

PS,.. I'm not insulted by anything here...
My comments may have been taken as insult...  I apologize..
I'm just saying what I believe to be true from reading the posts...
It is, perhaps, a difference in definition...  "easy swap", "direct replacement",...whatever...
The only thing that will bolt up exactly like a factory piece,...is a factory piece,... and even that requires that you have no other mods getting in the way...

Semantics aside,... a Harley, rail mount, muffler, without a crossover tube,... fits pretty well, and is an easy swap... and it sounds, looks, and works well...

Some people here, can not only rebuild an engine, but machine the parts to make one.... I can't....
Others here, don't change their own oil...
So,.. simple, easy,.... are relative terms...

If I think I'm being more harmful than helpful,... I'll stop giving advice ... I won't need to be told...

I have only one more thing to say,....
I can keep up w/ any of you's when it come to installing anything,.... my only beef has been the misleading statement of direct fit, when in fact there ain't a one of these mufflers that fits these bike like the OEM, or like they are supposed to. The ID ond OD does not match, nor does any one of them have the 7 degree kink in them to position them away from the brake hub, and let them slide on to the header pipe easily. No, I have not installed one, but I have seen, and measured enough of them to know they are NOT a direct fit. And its not like I have not done my share of muffler and pipe fitting in my day.
Yes, it is in the installers as to how easily you can make them "so called fit" !
If I was installing one, I would first of all machine a bushing for a "DIRECT FIT" OD and ID. (yes, I can do that) Then I would wedge cut the muffler inlet for the 7 degree kink, weld it back, and it would really be a "Direct Fit"

So, call it what you like, but I will continue to tell others what to expect when they ask, and are told the Dana's are A "Direct fit"

Me too:

No angle problems on mine either. 30-60 minute install, no adapters, welding or leaks.

Here's just an observation.  I have installed both a stock muffler and a Dyna muffler.  Actually just installed a second Dyna muffler.  I have not had to use an angle adapter, but I have had to use tin or copper shims at the muffler/header joint, for the Dynas.  There are two rotation points in the installation:  one at the header flange, the other at the muffler/header-pipe-joint.  Leaving all connections loose and using trial and error to get both rotation points at their most ideal spot seems to have worked for me
