Have you done any testing to verify the effectiveness, or lack of, when lowering the smoke stack? I figure you are the only reliable source of information available.
Thanks for any info you can provide.

Great question John.
I have not tested it. I have heard that some see a benefit so I am interested to learn more. I like what I hear about it but question whether the worst of the exhaust is properly exhausted when this modification is done. This winter I plan to experiment with this modification.
