I did a search and didn't see anything.
Are there drivability issues that I could have possibly overlooked or don't quite understand in regards to adding a TD header/tune and making adjustments with a TD afpr?

What adjustments do you mean? Set your fpr to 47psi key on and ride. The tune will take care of the rest. I don't believe you have closed loop or fine tuning... If your trying to target an AFR you would have to add fuel or remove fuel via the fpr.
 
A few issues may surface with that setup:

1. You will spend much time waiting for your Buddies.
2. Your Buddies will learn to hate you because you keep passing them.
3. This hate will metastasize, your Buddies will refuse to ride with you, and you will have no choice but to ride alone.
5. You will put a sticker on your windshield, "Lonely Trail Rider."
4. You will become severely depressed, buy a Ski Doo, and all the problems listed above disappear.


Lol

DMC, I wasn't exactly 100% sure. But also wanted to bring it up in case there was something else I forgot.

Must be lonely at the top. Can't imagine what it's like to have two sleds that go 150 Plus. Lol.
 
What muffler are you running with the header?
TD 3"SQ, to me, it's the best compromise between Flo and sound quality. It's not bad at all. If you keep the heat moving it will help limit detonation.
Get the best flowing muffler your ears can handle! While considering I have to contend with DNR in Wisconsin. Which I haven't seen them in "literally" 10 years
Note: turbo Dynamics is doing 10% off everything in stock.

45+ years as a ago little kid I remember reading a bumper sticker on a loggers pickup my dad worked for " If the devil doesn't get ya the DNR will"

Last time I saw the DNR I must have missed a check point or something. They had their pickup truck blocking the trail with another sled ready to chase me and one coming up from the rear. Lol.
St Germain Wisconsin....
 
There's already places where noise police don't even need to have you run your sled.
Just pull everyone over, have you raise hood or remove side panel. If the exhaust isn't factory stock, you get a ticket for modified exhaust. Doesn't matter if your sled is as quiet or quieter than stock. Modified exhaust = ticket!
They have an iPad with them that shows them what the exhaust should look like from factory. No sound test needed.

Haven’t seen one in Wisconsin in a decade either. But seems like the last 3-4 years I’ve seen them up by Munising area checking registration and trail stickers
 
I'd be ok with that cu, I'm legal but I still bet they won't like my 3" Sandale.
 
What is required to seal these fittings?
