Exhaust Ideas?

[KB9MBN]

Im looking into putting a new exhaust system on my truck, a 2017 Z71 5.3. As of now I have my old Flowmaster 40 SI/DO muffler dumped right before the read axle. I did this just to get a louder tone from the stock muffler. Well after driving it for a week now I've come to not like it at all. I have been looking at videos on youtube and reading around on different forums looking for a good setup in my price range, hopefully no more than $500, that I like. The sound I am wanting is a deep growl, not extremly loud but a deep tone. Nothing that pops when I rev high. Just a nice and deep at low RPMs and at higher RPMs gives a good throaty sound. Thanks in advance and I hope this wasnt too long.
