I seriously hate to have to ask this but someone has to..she whistle a little more? :lookaround:
He made a post somewhere that there was a noticeable difference in turbo whistle inside the cab. I doubt it changed the exhaust note though. I've ridden in a truck with this setup. It was an F-450 with about 15,000 lbs behind it. Truck had a 210 tow tune loaded up and the turbo sounded really good inside the cab.
