Re: Mufflers
Adapting any muffler type to the existing header will require some welding and/or fabrication. There is a good thread in ShopTalk that gives some details to get you started. 'Better/ easier' is totally subjective, depending on your wants, skills, and tools available. I don't mean to be rude, but we can't build your bike for you...

Re: Mufflers
You don't want mufflers from a fuel injected bike unless it had a separate catalytic converter upstream (like cars do). Member GLTriker used catalytic Harley mufflers and reported that they clog. Factor THAT into your decision. They are clearly marked as Catalytic.

Re: Mufflers
Did I ask anyone to build a bike for me? I am working on my bike on my own and plan to keep doing it. This is a forum where people can ask questions and if I dont know something I will ask questions (however stupid) than do something wrong. My question is genuine, I really don't know and ask questions because I want to know. If you dont like my question don't answer. It is easy to ignore threads like this.Track T 2411 wrote:Adapting any muffler type to the existing header will require some welding and/or fabrication.

Re: Mufflers
Thanks, I will look into it. I am sure the bikes the mufflers are off of are fuel injected.Earl43P wrote:You don't want mufflers from a fuel injected bike unless it had a separate catalytic converter upstream (like cars do).

Re: Mufflers
Older Sportster mufflers seem to bolt up easily, but some have different length mufflers, one is shorter than the other. Not noticeable to most, but they are different.
With an Aspy and bags, you will probably want the longer ones, just without the Cats.

Whatever I suggest here should be given ample time for a moderator to delicately correct. I apologize in advance.

Re: Mufflers
I used Sportster mufflers and all I need was a adapter to go from the headers to the mufflers.Track T 2411 wrote:Adapting any muffler type to the existing header will require some welding and/or fabrication.

No welding needed.
I also used a chrome sleeve I got at Auto Zone and made a metal bracket that attached to the sleeve and the rear foot pegs.
Was pretty simple and as I got the mufflers free, the other parts cost like $30 total.

Re: Mufflers
I was just trying to be funny, Freedom. Of all the motorcycle forums I have been in, I must say the people here are the most helpful, and nicest. Any muffler can be made to fit, but they should at least hold the same back pressure. Wonder why the Fuel injected Harleys are different?
