Not hard to install when you take your time. It took about 2 hours to install. Looks great, sounds even better. You can hardly tell when the engine shifts, almost seamless. Car runs better and RPM's are lower when at higher rate of speed. Not year sure about gas mileage since I only installed a couple of days ago.
