I've never had the intention of bypassing a pollution control device. What's the point in that (coal rolling idiots aside)? What I have had is the intention to improve torque, power, sound, durability, or economy (what I actually care about) which sometimes has the inherent side-effect of changing the pollution profile to be different than what the manufacturer originally shipped. But to say that I'm "really trying to [bypass pollution controls]" is at least one step removed from the actual facts.
I also think it's at least a little bit amusing that I can run a 65/66 Mustang with nothing more than a PCV valve (which is at least as much for my convenience in keeping the outside of the engine oil-free as it is for emissions), but in some states I can't put a cold air intake on a 2020 Honda.
I know someone that runs a tune shop in my small town and I'd say it is about 99.99% of his customers that are in for a DPF delete or bypass.
