First the instructions say 'unscrew', it's not 'unscrew'. You will need a hacksaw and some automotive knowledge. It's simple, but you have to know. This exhaust sounds great, but not annoying. I had my eye on some of the cat back systems but read a lot about people having issues with drones due to MDS so I decided to leave the standard 'bag' under the truck. Installs in about an hour. Measure twice, cut once. Overall I really like this setup.
