What a difference!
I must say the build quality and directions are fantastic.
I really gives a nice deep grunt when you get on it.
It does seem to eliminate a bit of the hiccup when accelerating from a stop.
I read a 5.4L Expy gained 11 hp after install. So, not the best bang for the buck, but it's something. Although the sound is my favorite improvement.
