My baffle looks the same as your damaged one. I was able to round it out with a pliers and sand off all the burrs. Looks OK. After I drilled more holes in the baffle, I took some sand paper and sanded the OD of the largest part of the baffle. The baffle fits really good now and I can remove it easily.

Thx for the info... I don't think I am going to put the stock baffles back in.. way too quiet. I am waiting for the AR-1005DB... cannot wait to hear them. But I will make sure to sand them off before put them in....

I too am interested in these baffles. Can someone give me an idea on the cost including shipping?

A question for Forchetto

Since you have used a modified (slash cut,) stock Arrow baffle and a cut down version of the 35mm baffle, can you describe the differences in twrms of sound and performance on your SE?

The cut down version sounded a bit better but retained a certain high-frequency component that didn't really sound like a Triumph. The performance seemed strangled by it as well.

The new, larger one sounds a lot deeper and when the throttles are opened they become a lot louder but far more pleasant, a nice deep rumbling sound with a great deceleration boom sort of sound.

The performance feels the same as without baffles. I imagine this is due to the considerably larger gas exit holes which don't sound much in terms of diameter, but what matters in gas or liquid flows is the area, this is nearly 90% greater with the 35mmDia exit pipe.

Does this same larger baffle (AR-11005DB) fit the Scrambler Arrow 2 into 1 ?

From past reading here about it, the 2-into-one standard Arrow baffle is dimensionally the same as those fitted to the 2-into-2 except that it has more lateral holes in the pipe section, so yes, a cut-down AR-11005DB will fit.

This is the 2-into-1 baffle:



And this is the 2-into-2 baffle:

Nice! I just ordered one from Jaap. He responded quickly via email and sent me a PayPal request. PayPal added 3% to the cost. 70 Euros. So, $90 including shipping to the USA. (Don't tell my wife!).

Can't wait to combo this baffle with a TTP Breathe, O2 removal, DNA air filter and a TTP Tune #2, which is also coming in the mail. Woot Woot!

Good information, Forchetto. Hope mine will arrive soon...
