Installation instructions are not the best but there are enough internet tutorials to get you through it. Be sure to mount the heat shields first and then mount the exhaust. Ensure that the rear muffler is fully seated with the rear header. Purchase new exhaust gaskets as well as Loctite and anti-seize. If you take your time and have basic hand tools this installation is not that difficult. Sound in my opinion is better than Freedoms 2 to 1. This seems to allow the individual pulses of the motor to come through giving it a cammed lope. There are those who say that 2 to 1 are better for power but I am not disappointed in any way. Build quality is good though the heat shield can still scratch easily. In the future, I will repaint them with ceramic infused high heat exhaust paint as my last ones turned out really good. Happy with this purchase though I had to wait quite some time due to backorder. Order while they are in stock; you won't be disappointed.
