The Gibson exhaust was pretty easy to install; it took me two and a half hours and this was my first time installing an exhaust system. The sound is exactly what I was looking for; a nice deep rumble that is noticeable but not intrusive nor tiring on the freeway. At light throttle or steady cruising, I can barely hear it, but as soon as I put my foot into it, I know it's there. It's a great product. I think the gas mileage is slightly better but certainly no worse. Hint: Use some type of lubricant when taking off and putting on the new hangers and at the slip joints. It makes it a lot easier to install.
