[Ducati] mufflers/pipes

[Alex]

What business is that?

I put a LeoVince 2:1 setup on my bike without removing the 
udder.  Dyno'ed it before and after (Cliff's Ducati in CT).  The 
difference was practically negligible -- about a 2% hp/torque 
increase with the LeoVince.

I decided I wanted to get rid of the udder (and the 15 lbs of metal 
it encompasses) and replaced it with the (5 lb) Sparks straight 
header and a Sparks dual side exhaust.  Put on a Power Commander and 
did the dyno setup again.  Difference was pretty stark:  The before 
setup with the udder and cored factory cans was 75hp/53 ft lbs and 
with the Sparks setup was 84hp/62ft lbs.  Ducati claims hp at the 
crank as 77 so I was pretty happy that I managed to get 75.

The torque curve showed a nearly identical plot for both, except the 
Sparks setup had the incremental increase.  The advantage of using 
the PC is the ability to adjust the fuel/air mix at every 
step.  Without the grid in place, it was hard to see the difference.

In my experience from the Dyno, the udder added nothing but back-end 
restriction, noise suppression and weight!
