Hi Rick, well these are the long tube headers and you have to cut the exsisting pipe to the front on the cat. You then have to assemble it all up and tack weld the flange to the front of the cat. Then you pull the pipes with the cats on them off the truck and do the complete weld. The headers stay on but loose until the final assembly. I have the Volant air bax and a Bassini exhaust on the truck as well. Used the Diablo Pretator to reflash and fine tune the system. Run's on regular gas with no knock retard at WOT. It is so quick it shocks first time riders with me. The shocks are great. Along with the polyurethene busings it handles like a cart. The rebound on the Edlebrocks is very fast, this translates to increased ground contact on bumps and dips on and off road. Pay attention to details and it adds up.
