Great post - thanks @jsobell
I got all I needed soundwise when installing the V&H offroads. Strangely enough, my Triumph mechanic told me that remap was not always necessary when changing the mufflers. I'm still not quite sure whether I feel a difference with engine behavior. Does that sound possible fellas?
In any case, I think I might go decat and will most probably hook up with Meerkat after reading your post. Thanks again.

They don't have to be independent, usually they are connected with a balance pipe.

Example from euro racing in bangkok:

Wasn't there a discussion (maybe a rumour) going around about the oxygen sensor on non-US Thruxtons being wideband allowing the ECU to tune itself while North American Thruxtons didn't have the self tuning capability due to narrowband O2 sensors? I wonder if that was ever proven or disproven?

I remember searching for information about the 02 sensors on these bikes when I found out about the full systems and what appears to be a lack of 02 sensor bungs on the headers, I couldn't find any info, perhaps that is true.

That would explain why no remap was necessary once I changed my mufflers.

I am curious if there is any difference in performance (or sound) to running one of the X-Pipe De-Cat products vs. the Straight Headers from Euro Racing. In Canada the difference would be about $400 CDN for the X-Pipe vs. almost $1000 CDN for the headers.

Thank you very much @jsobell for your post. Very informative indeed!

Mototrio Xpipe is only 85US if that's your bag, other companies are charging over double that.
