Xb9s exhaust mod

[Xb9 dan]

Hello from Denmark
just bought a xb9s and like the style and Sound and here you almost never meet a Buell it but i want a little more sound and have a spare 03 xb12 exhaust i want to modify but do i have to program my ecm ?
Thanks Claus

i have found as far as others say you might not need to reprogram the pcm. especially if it runs good and already has an aftermarket can on it. I can only assume cause these bikes don't sound good without a pipe. im not even sure the xb 12 muff will bolt right on, probably would thou

All XB mufflers have the same inlet diameter, except for the euro models

from my reading the 9 and 12 have different inlet sizes. so a 9 muffler cant go on a 12 and a 12 can go on a 9 but i dont think it will clamp enough to seal.

^^^^^^ what oh9bolt said muffles you can interchange but the pipes are different size at the heads, but at the muffler they are the same.

really, hmm

US version xb9 headers 1 5/8" primaries and 2" merge. US version xb12 headers 1 3/4" primaries 2" merge. I'm not sure of specs on Euro models.

i thought about getting a 12 muffler cause it has the valve and making it too where its always open on my 9 too make it louder. that way i would have my stock off my bike so i can send it to hawk when i get the money. then now down time.
