What to do with exhaust sound

Hey guys, I'm currently running 3" pipe after the cat into a y-pipe and and then 2 flow 40s into the tailpipes. It sounds good and it's pretty loud but I'm still lookin to make it louder. I had wanted to do true duals all the way but the guy at the shop said there was no way possible for my truck (2000 3.4 L V6) is this bogus or true?. I'd like to stay legal and not remove the cat or anything like that. But I was wondering what there is that I could do to make it louder and still sound good? I've heard about the flow super 44 muffler but i don't know that it's louder, or is there something i can do with my mufflers I have now and increase the sound? Thanks in advance for any suggestions.

How much louder does this make it? I wouldn't mind doing it really except that I just recently purchased the setup I have now and bought the pipe and tips and all. Is there anything else there to try? And would the super 44 even be worth the investment or is it no louder? And also thanks for the quick response +1

 

I don't know how much it makes it, but from what others have said it is very noticeable. Try youtubing some videos with with your set up with full tail and with it dumped. I've thought about it, but i'm happy with my sound at the moment. Never know i could change my mind in the future.
