What would happen if I took the exhaust tip off the exhaust pipe on a Yamaha Grizzly 660 SE and left the spark arrestor on?
(the tip as in being the very tip where the fumes come out)

the hot gases would be closer to items that it could melt---or your skin.

bazbikes4 is correct about altering the exhaust, however if it is just the tip and not part of the actual muffler core there would be no problems other than what other people have all ready mentioned (melted stuff).
If it is an older Grizzly that is not fuel injected you could run a straight pipe if you wanted. You would just have to change the jetting in the carburetor. This is what you are going to have to do if you go with an aftermarket system anyway, all most all these aftermarket exhaust systems will come with recommended jetting specifications, however they are rarely correct. Not only does the jetting depend on exhaust flow, cam duration, etc. etc... it all so depends on altitude and ambient air temperature. So basically it is all most impossible to be running the correct jets all the time.
If you do it correctly It will give you some advantage over a stock Grizzly, a bit more lower end torque and a bit more horsepower. But if you are not racing your Griz, I personally don't think it would be worth it.
I have a race quad Honda TRX450R with an aftermarket full exhaust system, it all so has air box modifications, a hotter cam, some head work, and a higher compression piston then stock. It is great and fast as hell, but for trail riding it can become irritating. It is extremely loud, there is no such thing as being stealthy with it. I actually plan on changing it and making it more quiet for regular riding this summer, it's just to much.

Do not, i repeat ,do not cut the end off your exhaust, this is part of the tuning and is made to a tuned length if you remove it you will have a loss in horsepower, you can take the spark arrestor off but do not alter the pipe. if you want a change then get a tuned after market pipe and that should help so don't listen to these people who give you such ridiculous answers just to score point i don't think they realize this is not a game.

Generally, loss of power and increased risk of water back flooding the pipe. If you want more power, look to an after market total pipe. You lose power because these are design to maintain pressure. Taking the tip of messes up the balance.

the tip just gives it more length to reach the outside frame part and lead the fumes to a safer place. its to not burn you or the frame of the ATV

As long as the resonator is still in place (that is the lump under the heat shield), nothing. It might be noisier but should not cause any other problems.

You would have a shorter exaust pipe. Not trying to be funny or anything but it wont make a difference.

Your vehicle would be louder.
