1999 honda shadow 750 ace deluxe had carbs rebuilt and when i put back on i split a hose ....... each carb has a hose about as big as a thumb and i was told it was a vaccum hose.... anyway will a split vaccum hose cause it to pop out exhaust went letting off gas

It's possible, the vacuum leak can cause a lean condition, which will pop out the exhaust when decelerating.

Sure can.

You need to replace the hose, it is quite important to the bike and the way it runs. Also, it will cause a lean condition that will destroy the engine in time.

Check here and see if it's one of these.
