It really isn't that hard to install, and theres no special tools required. All you need is a basic socket set, and a couple of open end wrenches, maybe a cresent wrench. Thats it. All you have to do is unbolt the stock Y pipe, take it out, take out the O2 sensor, place the Xerd pipe in its place, put the O2 sensor in, and tighten the 5 bolts. Done!!!
