The AR11005DB baffle is perfect for my Tec 2 into 1. I
did cut about 50mm off before installation.
I went here:
assumburg.nl-baffle
Jaap was the person I dealt with. Very helpful and
he spoke English.
I had the part within 2 weeks. Expensive,
but the bike runs great without being too loud for
the neighborhood.

Just ordered two AR11005DB from Jaap . He seems to be great, and well communicate. Thanks for the tip to cut out 50mm before installing..... How does the sound compare to the supplied baffles? I don't want them to be too loud after spending all those money.

The new baffle is 150mm long. Because it's also wider than the normal one it won't all fit inside, so it has to be cut to an overall length of around 50mm.

The sound is totally different. Louder than the normal one but nowhere as loud as going without baffles. At low throttle openings the sound is deep with a nice low rumble, especially on the overrun. On opening the throttle it becomes a lot louder, but it doesn't have those metallic, raspy, harsh overtones of open Arrows.

Forchetto, so they need to to cut to about 50mm in length not cut out 50mm.... The sound seems to be what I am looking for.... cannot wait. But I start to worry if I cannot get the stock one out...

Jaap at the site is very good to work with..he is shipping out my order tomorrow.

You'll get the stock ones out - just be patient. You said you got it to move about 1/16" ? Check to see if the cir clip groove is damaged from where the clip was removed. Other than that, try squirting a bit of WD-40 around the outside of the baffle, get a grip on is with some locking pliers and try a few gently taps while trying to twist it to see if you can break it free. Take your time and it will come out.

I cut mine down to approx.105mm overall length.
The tail of the baffle nearly meets the inner pipe
of the muffler. I might have trimmed closer to
50mm, but the bike sounded so good, I left it in place.
I imagine a shorter baffle might allow exhaust flow to fully
utilize the chamber at the end of the muffler.

I got the stock baffle out.... After 3 hours of hard work. Jaap provide me a good idea to grip on the baffle with a plumber pliers and hammer. It got the baffle started to back out till the lip line up with the pipe's end cap, then I used a locking pliers to grip the inner lip and tap with a 2 lbs hammer for another hour. I got it out, but it is damaged.
Any way, I am now looking forward to those 1005DB baffles. I am planning to cut them to 70mm, so they are not too loud to the wife's ears.
What do you guys use to cut the baffles? Pipe cutter?

If your silencer is the same as mine you won't be able to fit those 70mm in there before the baffle touches the internal gubbins. This is because the new baffle is larger in diameter. The original baffle tube fitted inside the internal pipe but this one won't. 50mm is the maximum I could fit.

I used an ordinary hacksaw but you can use a radial cutter as well. De-burr the edges well.

I measured the length last night, and I might only have 50mm as you said above. I am gonna try to keep them as long as I can. Anything to apply on the new baffles before installation? I don't want to spend another 4 hours if I want to get it out again.....

Some photos to share.
