I saw the thread on bsnelling muffler moding the 193t. I just bought one and want to muffler mod when the warranty is up in 3 months. Can I just mod the muffler or do I have to advance timing and adjust carburetor?

Just ask your Stihl dealer to order that part number there, and you don't have to worry about metal shavings working their way back to the piston.
I paid $289 at local dealer.
I don't get special price. Dealer is one of largest stihl dealers in US. Not mom and pop shop that has 1 or 2 of each model. They have 10 of each. They sell husky and echo too but prices are good but not as good as stihl. For stihl they let you choose any bar/chain for same price within the range recommended.
What do you mean get in sealed box? Dealer puts it together, fills with gas/oil and fires up. Warranty on top handles is 3 months per stihl website.
It was raining earlier so I was playing g with the 193t. Buried the bar in some hickory and it seems to be strong saw for its size. Only 2 tanks of gas so far.
The saw I just got - between paying full retail, barely putting out any bar oil(none would get to the bottom of the bar where the most friction is, it seems to have fixed itself however), putting a $35 gallon of motomix thru it, and it only somehow putting out ~80psi cold compression - is leaving a bad taste in my mouth. Even when the dealer was 'tuning' it, the thing would not just vibrate around, but 'hop' every now and then on the table like a racoon in a burlap sack. Ran like crap the first 3 tankfuls - chain would stop moving if you put any pressure on it.
The thing was almost impossible to tune right, it is literally just a fiberglass hair of a screwturn between spitting gas and sludge out the muffler, burbling, and running too lean. The fuel filter standing straight up instead of laying flat in the tank doesn't help either. Even went and got a PET-1000R to assist but, it doesn't work as well as the ol' earballs. I think I finally got it set right yesterday - got it where it has good power even with medium pressure, just burbles when I get the pressure off the cut, and the EGT heats up on a 'slow-curve' at WOT with the hottest point not being able to get uncomfortable on the forearm a few inches from the muffler port. I had been running it a bit fat for most of the gal so everything would be well-lubed during break-in and I don't think the rings set until I got it right yesterday. It was sucking air past the -ring- (btw, it uses only ONE piston ring, like the MS170), when I would put my ear next to the muffler I could hear it hissing past it. But when I went today and tried to listen for it before cold-start, it seems to be gone and the starter is much harder to pull slowly by twisting the wrist.
I just checked the warranty again, and seems you are correct, it is 3 months with no double duration applicable (1gal motomix purchase). Looks like I need to run this sucker and make sure its not a factory defect and get it well broken-in before then. For some reason I thought it said no warranty for top-handles, and only commercial/rental gets 3 months, hence the New-in-Box suggestion. However, personally after this experience, that is only way I would purchase another new Stihl in the future - bar, chain, and powerhead still factory-sealed.
I am a little confused. I thought the epa required the restricted muffler.
It starts to get up there (around 20-25psi per pull), but soon as it hit 90, it would drop back down to 75-80. I may send the gauge back to amazon, but I don't think the ear-next-to-muffler test lies. In your experience, should a saw this new have a small air leak past the piston ring on the compression stroke? I deemed it plausible due to there being only one ring on this new 193 design.I doubt it would run with only 80 PSI compression.
