im ordering my flowmaster 80 tonight so ill have it soon and its not gonna be installed till this spring. well my question is how long is and what angle are the pipes that come from the muffler to the exhaust tip? just to make sure gain i need 2.5 in and both 2.5 out right?

Dont worry about it at all. Most shops will put the muffler on and do all the necessary adapting automatically.

my uncle is gonna show me how to do it.

Then year, my Flowmaster is 2.5" im pretty sure, since NA tubing is 2.25" I believe. As far as what angle...? I have no idea.

SSEi'* are 2.5" in, dual 2.25" out.

how long are the pipes that come from the outlet of the muffler to the exhaust tips like what 12 in or so?

Measure them. My exhaust shop adapted my old ones right back to the new muffler.

ho wmuch do the stock tips cover?

How much of WHAT do they cover? :?:

They're not really tips, they're outlets.
