I jsut bought a 84 s10 blazer witha LT1 in it and it has headers and duals all the way back.....cats and mufflers on both sides. anyway on the drivers side it actually coes down and under the frame part where the tortion bars are connected. so you can see it from the side. but there was no room to go above it. the only things I can think of is a 3 inch body lift would leave enough room or i tcould be snaked around under the tranny to the other side til jsut behind the t-bar mounts then back over to the left side. anyone have duals and how did you route the drivers side pipes??
