I've got 1 of these on my xb9r, is it REALLY that much better over standard?
Just a noob question not trying to stir a **** storm or anything
IDK, let's see what the experts have to say about it:
XB9:
Buell Race muffler
The Buell Race XB9 muffler is a good RACE muffler. Its power band is decidedly skewed to the top,
and it is a decent performer in the upper RPMs as you would expect to see on the track. However, there
are other mufflers that have the same or better top end but have a stronger mid-range. The much
lamented “hole in the middle” IS there. And only the stock and D&D mufflers had less power at redline,
but just below redline the Race pipe makes decent power. The power at the very bottom near the pull
start is good until it hits the hole at 3500-4800 RPM. The Buell Race ECM has been tuned for this
muffler and this makes it a virtual bolt-on kit (a TPS reset is required). The sound is a little “smeary”
and “tinny” compared to some of the others that have more distinctive and staccato power pulses. Fit is
excellent, the chin cowl mounting is perfect, and the durability is good. Some users have complained of
rusting issues in some cases, but this is not any more of an issue than it is with the stock pipe.
Xb 12:
Buell Race muffler
Even more so than on the XB9, the Buell Race XB12 muffler is an excellent RACE muffler. Its power
band is similarly skewed to the upper RPM band. Its top end performance is better than all other pipes,
including the Micron, which only edges it out for peak HP in the final 200 RPM before redline. The
“hole in the middle” is still there, and from 3800-4300 RPM, it has the lowest output of all the pipes
tested, including the stock pipe. But it charges ahead of everything by 5000 RPM. The power at the very
bottom is also quite good until it starts sinking into the hole at 3500 RPM. The Buell Race ECM has
been tuned for this muffler and this makes it a virtual bolt-on kit (A TPS reset is required). The sound is
a little “smeary” and “tinny” compared to some of the others that have more distinctive and staccato
power pulses. Fit is excellent, the chin cowl mounting is perfect, and the durability is good. Some users
have complained of rusting issues in some cases, but this is not any more of an issue than it is with the
stock pipe.
