24. "What kind of performance increase can be expected from going to theFerracci/Staintune/Termignoni/CarbonTech/etc. exhaust canisters?"

Very little. The best application of the freer-flowing exhaust is in
conjunction with a jet kit and airbox modifications. By itself the cans are
estimated to be worth only 1 to 3 horsepower improvement over stock, with
little variation between designs. You could possibly improve that figure
using the "spaghetti" header designs offered by some manufacturers, but
that's another story.

However, the canisters lighten the bike by a bit and sound REALLY GOOD. For
instance, the Staintune aluminum jobbies weigh in at about 8 lbs. each,
which is a 22 lb. weight savings compared to the stock cans. You can expect
a bigger savings with carbon fiber. And we all know that carbon fiber is to
the Ducati owner what chrome is to the Harley-Davidson owner....

There are differences in sound between the various makes, so you may want
to listen to a set before you buy. The Staintunes, being made of aluminum,
tend to resonate with a "tinny" sound and can be described as mellow (but
this is not necessarily quiet). The CarbonTechs (and Pro Italia's house
brand, which are "unbranded" CarbonTechs), tend to be rounder-sounding and
have a "bark" to them. Some say they sound louder, although the author has
compared the two on identical bikes side by side and is not convinced. One
750ss owner recommends you purchase aftermarket mounting brackets for the
CarbonTechs application as they must be shoe horned into the standard
mount. Left for long, the carbon fiber components can separate. They can be
procured from PI Motorsports.
