I have an '82 and I need to upgrade the exhaust soon, the rust is barely holding the welds together. I have to replace my exhaust manifolds as well because we broke a couple of bolts when we put in the new crate motor. I am not going to be lowering this truck, I will eventually have some 32's or 33's on it, and I will not need to have a cat on it. I need to know some good headers, muffler (I am thinking Flowmaster 60 or 70 series) and pipe configuration. I have true duals and wish to keep it this way exiting the back sides at 90 degrees. I do not know what diameter the current pipe is, probably 2 1/2 or so. Cost is also a consideration, I do not have the funds for a top of the line system, so please keep in mind. Thanks, Brian Good lord. The rod up that man's butt must have a rod up it's butt.
