I had a louder dual exhaust on my Tundra. I loved it... except when towing. We go to Florida (almost) every winter and its a 2000 mile round trip towing. Last year with a 14 month old daughter the exhaust was too loud. She didn't nap because it was too loud. As soon as I got home,, I took it off and put back the stock exhaust.
If you want to go back to quiet exhaust for towing, check Tundrasolutions for someone trying to get rid of a factory single exhaust. They flow well and are quiet. You can probably find someone willing to pay for yours, whereas you can probably find a takeoff for free.
