Great product. It can be a little loud when you put your foot in it but I like that. I think it did give it a little more power not a lot but any helps

I installed the aFe Magnumflow ProGuard 7 on my otherwise stock 2012 6.7 Powerstroke. Power increased as promised. Fuel economy increased on the highway, but is worse in town now, assumedly from the increase in power. 18.5 in town 20-22 cruising the highway.
