GT2000 year changes
 

Bought a 2011 in generally better condition than my 2013 GT2000.
What things might I want to switch over from the 2013 that are a better design, better part etc etc?

What's the black disc on the back of the wheels for ?

Why is the exhaust pipe on the 2013 so much larger than the 2011?

Can anyone comment on the exhaust?
Surprised to see the frame/hinge design is different.
Did the CH640 go to a larger exhaust from 2011 to 2013 to increase the power or do I have something weird here?

My 2018 XT3GSX has the Larger exhaust Pipe as well. I'd say it was just a selling gimmick on MTD's Part :ThumbsUp:

Figured it out
 

The exhaust is not bigger on the later models. They just run the small exhaust inside a larger tube the surrounds the small tube. So weird for a company that looks to save pennies everywhere.

Is the larger pipe a heat shield around a smaller inner ?
I would guess at the black disc being a brace/strengthener for the wheel
