Exhaust mod….update

I am looking to get a deeper note from my exhaust without being anxiously loud, a few decibels louder would be ok. Slip on’s such as the Looney Toon & Big gun are too loud & the HMF swamp series is to fricken expensive here in canada, $550!!!
I searched "exhaust mod" & only found a couple of older threads. Looking for some feedback on riders that have been running their own exhaust mods to try to find the right mod configuration to use.
Thanks
