One theory is the different lengths of the head pipes. Could be,...but I never really thought about it .I made it work with a small restrictor on one pipe

Whatchu talkin' about, Willis? I have not heard this! Why would that be? They service two identical cylinders originally.

This is true.
but on the Harley, the pipes coming out of heads are different length, and the heads run at different temps. Its really a tuning issue. They will work on a Wing just the way they are. The pulse of the two cylinders on each pipe is off set by the crossover, . Even without a crossover they work well enough on a wing. On my 1200 I run a stock muffler, with a sportster take off on each side. Brings the tips out beyond the saddle bags. I removed the tips on the GW mufflers, and installed the sportster pipes. Nice and quiet, and the bike still has great power

I'll be danged. Well, as you say, there's no noticeable effect on how the wing runs with them. Mine sure seems happy.

Thanks for the info! I sure missed that memo - but it sounds like Harley to do that.

With an Aspy and bags, you will probably want the longer ones, just without the Cats.
I got the bags off. I am worried about the center stand though.

I used Sportster mufflers and all I need was a adapter to go from the headers to the mufflers.

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.
Thats interesting. Do you mind if I PM you for more information?

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.
I'm sorry, you're absolutely right. Frustrations of the day, I suppose, which you did not deserve to be the brunt of. I apologize.

That said, I would like mention that, unlike the 1000's, which have a slip-on/clamp header to muffler joint, the 1100's joint is welded. There is no flange on the outlet end. The header is also kind of D-shaped and tapers quickly to the outlet. A typical exhaust adapter or reducer won't readily clamp to the header (yes, I've tried, lol). As you also listed your bike as an Aspy, if you are running the saddle bags the angle of the outlet needs to be considered.

I was not aware of these facts.

Good to know.

Wonder why they went that route, seems they just made it more complicated.

Yep, and that joint, especially on the fuel pump side, is the first thing to rust out. I haven't found a good way to repair it that doesn't look like doggy doodoo, either...

Freedom, please don't take what was said personally, these fellows are great helpers. My comment was a humorous self deprecating comment cause I fumbled my build along. You should see what I did with the clutch for example.

Cyborg, yes you did offer and if I had been closer to your location I would have been more inclined. However, I am proud of what I came out with and I am not done. Anyway, I thank you for all the help you have given me personally and through this forum in general. Now, Back to mufflers....take it away!
