I put my exhaust on and now my car stalls and has little vacuum?

1984 camaro with 305 engine in it. It ran good when I had headers on it, I go and put a 2.5inch true dual exhaust with glasspacks and now it has trouble starting. When it does start my vacuum is less than 10 and the idle is extremly rough. After maybe a second or 2 it stalls unless I hold the gas down. Any suggestion?
