Exclamation How to solve the problem

I just put Hooker headers, with a 3" dual exhaust with no mid pipe, just straight back..Sounds nice, but i get these horrible popping noises when im usually in 1-3 gear..And sometimes it backfires...Am i running rich?...Or too lean?..It never did that with my stock stuff on there, only now....I dont have a exhaust leak at all, but there is something that is causing this..Need mad help....
