It can't be the mufflers, the quieter ones would have causes more restrictions on your flow those would be the ones that caused the problems. When I took off my manifolds and put on headers the system would backfire also. Try tuning your carb and your fuel flow, just remember that every little thing you do to your engine will affect another part. I would go get it dyno tested, those guys over there know there stuff, often it just needs a little twist here or there good luck!
