Not a good thing for many reasons , Up to and including backfiring
Look at Delvec ( probably spelled wrong ) Better pipe IMO
OH and welcome to KZR

Why do you say an open baffle is bad? (apart from the noise). With a 4-stroke engine, the valves are all shut during the compression stroke, so you don't need any external pressure to get good compression - the cylinder is effectively sealed.
Popping and crackling on over run is generally caused by unburnt fuel in the exhaust gases. This will only ignite if there is the addition of air from an exhaust leak.

Noise is biggest as a crazy loud bike can cause more non riders to want our bikes banned from areas.
Tuning issues Most , / Not all bikes run better with open pipes... A little back pressure. doesnt hurt
Open headers are for racing where I would tune for max power . Biggest cams , biggest ports and valves, etc ...= poor fuel management / mileage.
Now all that being said So this makes me a hypocrite ...As . I run a open pipe LOL But mine is on a turbo race motor and I also run a LONG tailpipe to control noise and it works quite nicely Short pipes contribute to more noise . Some will also warn of the exhaust valves being exposed to cold air when motor is turned off and could warp the valves Just My 2 or 3 cents
PS This should spark some opinions :lol: :lol: :lol:

That's quite a sweeping statement. You won't help them based on what? Noise pollution, or that anyone with an open exhaust is anti social? or just oiks? or some other reason?

I thought about where my opinions are rooted
In my 50 plus years of being a motorcyclist I have had to many negative experiences with open headers and straight pipe bikes.
Most bikes I have had to put a hand on with open pipes have more wrong with them than right . Examples are lack of good tuning and maintenance.
Hey Dave , fix my bike . OH no air cleaner / cheap plugged pods, / Never jetted right / air leaks etc. Valves off. Never change plugs never set timing or change points . BUT boy does it ever sound great LOL SO I get it running and the first thing they do is blast around the town at Mach 3 with their hair on fire and a big smile.
Pipes are red hot and the finish is cooked off from the raw fuel igniting in the pipes. And all this is best case because at least they had me sort thru the drivability issues.
NOW No holes in my hands as I was once that guy . As Ed said it , Now I wont touch a bike like that as the mentality of this personality
Is now they think the bike is the fastest in the world and need to prove it by setting off car alarms and rattling windows after midnite LOL
Usually the bike ended up broke as super biker never checks his oil.
Sorry , but I am jaded

Noise pollution. And a good many people running an open exhaust don't care if they annoy people with their noise, an attitude that I choose to not support.
