threre amazing, best bang for the buck man,
i have bought one from him and it was amazing, but mine was for my h22 ef hatch and it was pretty much
destroyed due to being a really low motor and really low car, but that is expected with all "header" that i had on my slammed car.
so my conclusion, run it, its a badass header for 1/2 the price then the top companies, and it has mostly all the same gains.
but this is just my 2 cents, so everyone will have a different opinion!
