Flowmaster 40s vs glass packs/cherry bomb

My engine is a 350 SBC with thumpr cam, right now I'm running flowmaster 40s true dual no X pipe off stock 1985 manifolds. Don't get me wrong I love the sound the 40 series makes I just want more a throaty pop pop sound that muscle cars used to sound like.

Can you all shed some light on info on glass packs/cherry bombs?! Maybe some pros and cons and some brands to choose from. Not 100% on switching out, but I might get convinced! Cheers

Edit : I DO have serious drone right now with my setup, looking to clear that up as well possibly. Maybe not, I have pipes 90' in front of both rear wheels :O
