Bought my charge pipe from Eric last week, and I love it!
Install was pretty easy for me, most time consuming part hands down is taking all the torx screws out.
Fitment is perfect, look is awesome, and though the power gains aren't huge, you can definietly feel the acr pull a bit more.
Highly reccomend the Envy Charge Pipe and Eric@PYSpeed!
