I am going to get a modified exhaust, but I really don't want to chop up my almost brand new stock one, so I'm looking for a donor muffler. I read somewhere that the XB9 muffler will work just as good as an XB12 for that purpose, main difference is that it does not have the exhaust valve. Is that correct? That would broaden my options. | ||

I believe the XB9 has a smaller inlet connection, so it wouldn't work. | ||

XB9 pipe will work if your getting a drummer, but not for a special ops. XB9 pipes do not have the exhaust valve. | ||

I see, Special Ops still uses the exhaust valve so it would not work with a muffler that is born without it, but the rest is the same so a Drummer is still an option since it disposes of the valve anyway. | ||

The primary tubes are smaller on a 9. Collector size is the same. Back in the day, a Buell race muffler was a Buell race muffler, they fit either a 9 or a 12. Only difference in the kits was the software in the ECM. | ||

Awesome, so since the inner tubes will get gutted anyway it's safe to say that the XB9 muffler shell and XB12 are compatible as far as being candidates to become drummers. Right? | ||
| Ratbuell |
Correct. On the muffler the only difference is the valve and internal routing. Shell is the same. | ||

Internal tubes are actually larger on the 9. XB12 = 1-3/4 x 1-5/8 x 2 XB9 = 1-3/4 x 1-3/4 x 2 If you are making your own muffler, I recommend leaving the jacking point supports in place. |
