    Not bad sounds good

    Instructions are straight forward have to figure out some of the hardware on your own. The new vac hose they give you could be a little bigger in diameter and the fitting for it should be metal instead of plastic since I broke it trying to get the hose on.The metal nut molded into the intake for the fitting seemed a little loose as well. All in all after some minor modifying and getting it installed the way I like it, it looks good and added some pep and sound to my truck.

    Very easy installation, about 45 minutes. Everything matched up as described in instructions. Great sound on a 2004 Explorer 4.6 V8 with a series 50 muffler.
