I am not 100% sure if an electric clutch will fully disengauge the fan. I am sure the electronic clutch does a better job of disengauging the fan than the thermo clutch.
Around 2008 GM went with an electric clutch to improve fuel economy over the thermo clutch.
A thermo clutched fan sucks down around 4hp off the crank at highway speed, when you dont need it to.
Plus with the fan not turning your engine warms faster in cooler weather.
The X-pipe scavanges exhaust better than any Y pipe or true duel pipe setup.
If you turbo, go with the biggest pipe that will fit and run it the shortest length you can get away with.
