Installation is a Snap:

This pipe slipped right in. it gets a 10 for installation. The pipe comes with bungs welded in for the pressure sensor, but no hardware to plug the holes if your not using them. would recommend picking up 2, 3\8" pipe plugs before you start installation. So far, i have not noticed any fuel mileage gains. awesome horespower....
