Yes I installed it myself. I have the 4 inch stainless steel turbo back exhaust, it was not too difficult to install. I had to keep everything loose when installing the down pipe, very little room to work with there. I tore the heat shield material a little but repaired it. My down pipe is one piece, and it was a PITA to get it to fit right, then making sure I had clearance everywhere. Once installed the big thing was re tightening everything and re adjusting to make sure it was all good. I deleted my Cat, not sure if it helps but I am disgusted with smog restrictions and my truck seems to run better without it. I painted the pipe black,(high Heat flat black paint) from the end until it tucks up over the axle. It looks really awesome. Not alot of trucks like that and it is good looking.
