WHAT IS IT? Instead of using available tubing, Scalvini
hand-welds over 40 different cones into their 2014
CRF450 exhaust system. This is a labor-intensive way
of making an exhaust pipe, but it is the Scalvini way.
WHAT’S IT COST? $1750.00 (Ti head pipe, Ti canister
and carbon end cap), $1350.00 (stainless, carbon end cap).

WHAT STANDS OUT? Here’s a list of things that
stand out with the 2014 Scalvini Honda CRF450 twin
(1) Performance. It’s no secret that the 2014 Honda
CRF450 is not a muscle machine. It makes its best power
from 6000 rpm to 8000 rpm and then goes flat as an
ironing board. Every test rider wants to trade some of
the CRF450’s abundant bottom end for more mid-and-up power, and that is exactly what the Scalvini twin
Below 6500 rpm, the Scalvini pipe is weaker than the
stock Honda exhaust, but once the rpm climb above
7000, the Scalvini pipe takes off.
( 2) Dyno runs. MXA’s dyno runs showed that the
Scalvini had a horsepower loss from 4000 rpm up to 7000
rpm. After 7000 rpm, the Scalvini makes 2 horsepower
more than the stock pipe until sign-off. In back-to-back
runs, the stock pipe produced 51. 97 horsepower, while
the Scalvini pumped out 54. 20 horsepower.
( 3) Parlor trick. Because the Scalvini gives up
horsepower below 7000 and makes more power above
seven grand, the powerband hits very hard. Given that
it goes from nothing to 54 horses in the blink of an eye,
the power delivery is very abrupt. It feels more powerful
than it really is. Amazingly, most test riders liked the
way it felt—even though there are aftermarket exhaust
pipes that make more power than the stocker (and the
Scalvini) from idle all the way to sign-off. They just don’t
have the brutal hit!
( 4) Two into one. The all-titanium Scalvini starts
as a single pipe at the exhaust port and breaks into
twin pipes—one down the left and one down the right.
Additionally, the left-side pipe is shorter than the
right-side pipe. The long titanium mufflers are painted
black, for some hard-to-understand reason, and are FIM
112 decibel legal.
( 5) Installation. Don’t ask. To make the left-side pipe
fit, we had to remove the chain roller and some electrical
bits. We rerouted everything without any glitches, but it
is a little Rube Goldberg. And, Scalvini’s P-clamp design
can be a jigsaw puzzle to line up.
( 6) Cone pipe. We love the look of cone pipes, but
they add to the price tag. Beyond a shadow of a doubt,
this is an exotic exhaust system.
WHAT’S THE SQUAWK? Lots of mounting issues,
but eventually it fit. Also, let’s not forget the price.
There are better CRF450 pipes, but there isn’t

a wilder-looking exhaust on the planet.
