Hi talkriver:)
did you change the air filter as well as the exhaust?
As a second step, did you remap the ECU or did you just install the emulator?
I switched the stock filter to a Sprint filter.
I flashed the ECU with RexXer User tool. The map was created and sent by RexXer according to my information that I installed Arrow Pro-Race exhaust and Sprint filter. Writing RexXer map into ECU avoids alert which shows exhaust valve servo missed. So I didn't have to plug the eliminator into the valve servo connector.

perfect!
I'll have to wait for spring then I'll have the mapping done at the desk (dedicated map).
It will also be useful to replace the air filter

Have you decided what tool/method for mapping and flashing?
If not yet, what option of tool/method are you considering about?
I was thinking of buying a heal tech D02 servo eliminator and having the original ECU mapped at the bench. In northern Italy there are many installers who carry out the recalibration by varying the parameters due to polluting emissions. I install the servo eliminator in case I want to return to the original exhaust (obviously I make a copy of the original map in case I have to go back to basics)

It is nice that a tuning shop is there around you.
Hi Talkriver. I've watched your YouTube videos and it sounded like you had the best results with the little Cat DB Killer? I've got an Arrow on order and I'm concerned that it may be a little louder than I want . I plan on taking it to a very well respected dyno tuner , once fitted and am thinking of getting one of the same dB killers you have to give me options before tuning. Can you add any thoughts on the benefits of the dB killer?

I think the benefit of dB killer is just loudness reduction.
When rode Diavel 1260 which equipped Arrow pipe without dB killer, I felt less distasteful shock of engine brake than before switching stock pipe to Arrow pipe.
When put my dB killer into Arrow pipe, the shock of engine brake turned back a bit.
You'd better ask the tuner to damp out engine brake if they can.

I got a DB killer pictured below and tried instalation then succeeded. View attachment 112360
You can easily find this kind of cheep DB killers at eBay.
See attached cross-section diagram. View attachment 112361
DB killers which diameter are 60mm can be put in the silencer then is held.
But my bought DB killer could not make loud less as expected.
I modified the DB killer like pictured below then am using. View attachment 112362 View attachment 112363 View attachment 112365
hi talkriver
I bought the db killer (the shorter one, in the first photo). I tried to insert it in the drain and I saw that it doesn't block but goes all the way inside. In your drawing, I see that it indicates a 58 mm step inside the motorcycle exhaust but the new exhaust doesn't have it. did you add it with some accessory?

It is unexpected.
My nichrom silencer didn't require any additional part. Photo shows my silencer taken when I had got.
Gas Carbon Audio equipment Auto part Home appliance

You probably see ring-shaped step.
We can see similar step on full titanium silencer of Voodooo's as shown post #18 of this thread.
Arrow revised structure?

.on my exhaust there is no internal ring.I think of a production error.
I will have to evaluate another type of db killer
Hmm...I agee that no ring is Arrow's error.
Silencer wouldn't be locked on loop pipe. Once engine starts, I guess the loop pipe will constantly stroke in the silencer. I worry the stroke would damage pipes plus mounting point of the silenser.

My math tells me that the Arrows I went with give a weight savings of 7.11kg or 15.6 pounds.
15.6 lbs = @ 1.6 HP extra. Just in weight savings, then the increase from better flow...and that sound...looks great!
Ya done well.

Ever pull up to an outdoor bar in the tropics and have someone across the bar yell: "I though I heard a DUCATI coming, farang!"

Yep...Ducati in the House.
