69 cuda with 360 stroked to 410 Way the hell to loud.

The car was being built to be a drag car, we got it and got it useable for street the exhaust was all already on it.
The car has roughly 600hp, and is using flow master 40 series mufflers. Any mufflers i can easily chuck in there to quiet this thing down? Driving for an hour and your ears ring. You cant have a conversation standing beside it idling.
