I just put on a set of Long Tube headers last weekend. Along with the Magnaflow and the dual 21/2" outlets, the truck runs pretty strong for a 5.3. Went to verify the tune after the headers and it was not off very much from what we left it, last spring. I still believe the 3.42 is the better rear end gear ratio.
