Big difference between flowmaster 40 series and 40 series delta flow???

I have true duals on my TBI 383 and i went with Flowmaster 40 series delta flow mufflers. I was expecting it to be pretty loud and deep but i am sort of disappointed. Its actually pretty tame and quiet and it just doesnt have that deep sound i was looking for. Running long tube headers and no cats. Do you think a switch to a true 40 series muffler would make much of a difference?
