Uilleann pipes are reed instrument, you won´t get similar sound from any whistle.
However, my Overton in E (low E) has a nice edge - it´s described as “cosmic drainpipe” (probably difficult to understand, once you hear it, it makes sense).
Something that sounds rough, or edgy, without having tuning issues. Maybe the beast doesn’t exist, or maybe one of youse has one.
I’m after someting that’s the antithesis of the breathy Chieftain V3. Perhaps its cheapo. Perhaps it’ll cost an arm & a leg. Perhaps its got a difficult stretch/big holes/small holes:
you could always find out if there are sessions in your area, or other whistlers, and ask if you can try out a few others.
If you don’t like what you find it may be possible to get a maker to custom-make a whistle. I know that Ronaldo Reyburn can do it. Colin Goldie will customise. I think Mack Hoover has dropped out of whistlemaking for right now. Daniel Bingamon is another possibility, he loves to tinker and experiment with whistle design.
You might be talking about what I call a whistle that “honks”.
The best, for me, is the Burke Pro Viper. No low D I’ve tried has a bottom D that honks anywhere near as full/strong/loud as the Viper.
