Really simple installation with basic tools. I did have to cut the stock exhaust to get it out from under the truck - driveway installation. The sound is great - louder than I wanted, not by much, but at start up its got a good bark. Sounds great going down the road. When truck goes into 4cyl mode it doesn't sound bad at all. There is no drone whatsoever at any speed. It is just what I was looking for - truck now sounds like it should!
