I just raised the bumpers on my '91 K5 with a 3" body lift. Now that they are raised I am ready to put on the dual exhaust. Going to be running dual Dynomax 2.5" inlet/outlet mufflers and put the exhaust out each side behind each rear tire. Now that the bumpers are moved up I want to raise the exhaust as well to cover up the now exposed rear spring hangers, and also to tuck the exhaust closer to the body. Do you guys think I will need a heat shield around the pipe where it goes between the spring hangers and gas tank? As it sits currently, the pipe is 6" or so away from the gas tank, but if I tuck it between the two it will be only a few inches from the gas tank. I was thinking of using this as a heat shield: http://www.jcwhitney.com/autoparts/...006315/N-200005084+111+1990+600012697/c-10614 Anyone have any suggestions as to whether that is needed and if it is a good idea? If I run the exhaust out the passenger side as well, what are the things I need to be concerned with as far as keeping the exhaust away from fuel lines, etc.? Thanks for your help.
