What would be the best muffler for me?

I have a 89 F150, it has a 300 straight six with a 5 speed. There are so many aftermarket mufflers and i cant pick one. I want a muffler that is deep toned but not really loud when you punch the gas. I want it to be noticeable when it's idling but i dont want it to be so loud that the whole town hears me when i punch the gas. Any suggestions?
