Finally got around to shooting a couple quick videos of my Borla Catback. In the one from inside the truck you can hear my Volant too. I really like how it sounds. It's not too loud but enough you know it isn't stock. I only had 200 miles on the truck when I installed it so not sure about performance gains or mileage increases but I suspect it wasn't much.
Here's a link to the vids
