If you have it type approved in the uk would that help prior to export would that help or does it have to be tested in Denmark ?

It has not to be approved, but it is not allowed to make a lot of noice. As far as I remember the volume should be lower that 90 db. In doubt the officials have an instrument to measure the volumen.

Kind regards

VOSA (the uk vehicle testing agency) do have noise meters and can road side test bikes in the uk
But most of the time they don't bother.

Have you seen the "DB killer" baffles that are available ?

They bolt in and reduce the noise significantly. They do increase the back pressure a little but not significantly. They are how most of the "removable baffle cans" work.

If you google DB killer
you get

All of these should do the job or be able to be adapted to fit with a bit of work

Hi Duc750,
What a brilliant idear
A simple solution - i will give it a try.

Thank you so much

Kind regards,
Jacob

Jacob, I am very sorry, that i cant sell any pair, cause soon i try put both my Pasos to my "museum" and i have two kids(11 & 14)and i let Pasos to them, WHEN they know exactly, what they are sharing, not before and i think i want to help also them then with they Pasos and surely they also want to change pipes and test, etc... allkind mufflers in they Pasos, so pitty, that i cant sell any pair now...

To "noise killers, etc"... : I think every country have local rules about mc noises, so better first look them. I have earlier writed, how it function in Finland in some topic. Anyway, if country have somekind "early check"(what not yet in Finland :funny: ) Its very simple to buy/put metal "net" inside to mufflers, when its time to take bike to "year check", after easy to take them away and again You can enjoy nice/loud Ducati sound, BEST EVER sound in mc world!!!

No probs - It was just a try

I will buy a db killer or even make a light version from steel wool and metal net. But thanks for your respons

Finnpaso,
If you have the smaller exhaust pipe size, at the point that the slip ons mount to the pipe, would it be possible to use a 2 mm (36mm to 40mm) shim or collar to make up the difference in tube size? For $500 to $750 that the Two Brothers cost I hope they are lighter, increse horsepower and are better sounding than anything else!

Doug

Mine are bigger ones (40mm) and its only good way to change headers to better flow 40mm ones and then connect pipes directly to those, without any shim or coller. And You cant make more hp, if only change better flow pipes. NEED also better INTAKE AND SURELY MORE FUEL(richer mixture!!) to get more POWER! If change only to free flow pipes and not change fuel mixture, then Your exhaust valves can burn, what is not so nice to look I have seen some such Ducati cases

NEVER more hps WITHOUT MORE FUEL!!!!

Finn,
Are all 750 exhaust ports large enough for the 40mm headers or do the US models have to stay with the 36mm? Can you change any Paso 750 over to the 40mm headers? What jetting changes are required?
Doug

ALL 750 Pasos have SAME exhaust hole in sylinder heads, and connecting flage measurements are same, so no any problem to fit 40mm header pipes to 750 Paso. Worst thing is to find such 40mm headers! Surely need rejetting, if put open pipes to Ducati. But this is not very simple thing, so it needs long story to tell, but if i say it "simple": all open exhaust/inlet system modifications need rejetting. But with Weber its not so simpple thing... no!

Ps, i dont know exact USA Weber jettings, but i can find from my notes, what jettings are very close to EUrope Paso with Weber and 40mm headers....
