Nice write up. I have a Megan header and the fitment is great. There are no leaks that i have found but it has started to change color a bit which im not a big fan of. The gains are as stated pretty much top end. It does give a bit of a different tone aswell. Im currently not running any other exhaust but the header but that will soon change
. Hopefully others will post there finds with there headers and we can keep this going.
