Paso muffler cross reference

bf-fly · Post by **bf-fly** » Sat Jun 09, 2007 5:26 pm

Does anybody know which mufflers other than those specifically for the 750 Paso (or 906/07) are easy to modify to fit the 750 Paso?

There are tons of mufflers available for newer bikes that have a chance to fit without major rework. Do any of you have experience trying to do this? Any suggestions? Stock rivet type is fine since I'd just open them up and and reduce the internal baffling.

Here is two examples:

http://cgi.ebay.com/ebaymotors/Ducati-9 ... 3936QQrdZ1

I can modify the cans as necessary, but the where pipes meet is harder to get a nice fit and finish. Aftermarkets with the adjustable mount like the first I posted seem to have the best promise. I can use adapters as necessary for different diameters if I have to.

Any suggestions would be appreciated.

it's an hard work to fit such mufflers on paso pipes.. You might think I'm fooling you, but I can say it's not so easier thanbuilding your own mufflers starting from zero!
It's very cheaper buy iron cans in an "acme" store and design the best muffler you can image! Afterwards, you can match the same on stainless steel, lighter and nice looking!

Here're the links to mine:
50 mm out
inside the muffler
It's still not so nice to see, but...SOUND GOOD!

Ciao Nicola,

really, I can't believe too

!
Have you tried them for their effectiveness? I knew the mufflers when not well "tuned" could lower the engine power etc.

Ciao

Actually the 2 in1 was jet intalled on the bike, but the 50 mm to 40 muffler wasn't able to make the engine run correctly, so I designed and built a new muffler following my ideas about exaust flowing, and it runs very better than any other I tested on my dukess...
Anyway, following the same idea and choosing the right diameter for the internal cans, I think that you can build your own 40 mm couple of mufflers

You only need to leave a regular "front surface" (what's the correct term for this???) of the 2 in 2 pipe that should be
[(40/2)^2] x 3.14= 1256 sqr millimeters
so the secondary can should be about 60mm diameter
and the external cover about 75 mm
for a total lenght about 400 mm;
then try to cut a small part to reach a better flowing
Try to believe!

I have 2 stock sets of mufflers. My plan for now is to cut open the bottoms/backs of a stock set , Say about 2 1/2 inches (6-7 cm) by about 14 inches (35cm) remove some of the internal baffling, then weld it back shut. Smoothy finish then repaint. The parts I cut open will be on the underside and back, hidden from view but nicely finished.

What do you think?????

Piero, your bucefalo runs smoothly?
My dukess needed 2500 rpm at idle and 5000 rpm to start at green trafic light wiht the wrong muffler and a bad carb setup!
Previous owner should be very sad about this!

yes very smoothly 1100 at idle no esitation to max rpm

i have mikuni with hand made air box....the bike goes great now....
i have the original paper filter now not yet the bmc but the bike goes better now.....
