I'm going to try the super turbos with the tail exhaust, and see how it goes.
If it still doesn't sound right, I'll leave the tails in place for future use since they're hung at both ends. Then just put the 45s back in until I'm older lol.
I really loved the way it sounded. And it didn't actually drone. Just with no AC and the windows down, the side exit was too much on a road trip.
