In definately sounds interesting. I do not like the drone. There are benefits to having a new truck and being quiet is one of them. I had a 90 454ss that the exhause was tucked under the bed, it was pretty loud. I wonder how well the VT works. $100 isnt too bad for a muffler, and pretty reasonable if it actually works like they say. I'd hate to break that valve and then end up with a loud drone and a rattle.
