Never again will I buy a product from Pacesetter. The first set of PS headers I installed had uneven flanges and leaked. I even tried two gaskets. I eventually took a belt sander to them and fixed them. The second set was on my 08 Z71. They say they are for 4x4. I would like to ask them how, because the o2 sensor points straight at the driveshaft, 2 inches from it. I took my truck to an exhaust shop today to have the o2 bung blocked off and a new one put in. I had to actually put it in the curve of the Y pipe, 5 inches from the collector to get it to fit anywhere. I am not satisfied with this product whatsoever right now. I aslo bent my dipstick tube in the process of installation, so this turned into a $700 budget header install. I could almost have gotten Dynatechs for that price. I am not happy.
End rant.
