Arrow cans baffles in or out?

[TonyG]

Hi,

I've go some Arrow cans on my 2009 M1100s. They are fine with the baffles in, have not changed anything else on the fuelling, no map change, etc., and it runs perfectly. However, I've just found my old circlip pliers and I'm tempted to try without the baffles. I don't want it to be too noisy, but if it's acceptable with them out is it likely to need the fuelling tuned? Should I just try it and see how it runs?

Cheers

I had some hi level arrows on an IE 750 and also some on the little priller .. With baffles out they were loud on both, how offensive depended on the listener and the time of day.

One local used them as a fall back wake up alarm from about 150m away and behind double glazing.

Try it and see, if you haven't done anything else to the motor/inlet tract the fuel map should have enough flex to adapt to them.
