Pacesetter Ceramic Coated Long Tube LS1 Headers & TSP or Pacesetter Off-Road Y-Pipe Combo!  The Pacesetter long tube headers will come standard with new gaskets, bolts, and wire to manually extend the front O2 sensor via cutting and splicing.  We highly recommend using the plug-n-play O2 extensions so you do not have to cut any of your wiring and can maintain a good O2 reading!
