I am looking at getting some long tube headers. Does anyone have them or can remomend some for my car. I have a 99 mustang and not that many people are making them for the 99+ stangs. Also need to sell my exhuast if anyone is intressted pm me I will also put them in for sale forum. Anyway any knowledge that people can give me on the headers would be apprtiated. Also what is install time on them?
