[QUOTE="Oldtimer, post: 1011502, member: 65912"] Allen, I have an '07 V8 and have full dual exhaust on mine. What you have stock is 4 cats and one muffler. There is also a "Y" tube to bring the two sides of the exhaust into one pipe to the muffler. When I had mine dualed out, they removed from the "Y" to the exhaust pipe. the pre-cats and cats remained and the piping over to the Y tube remained the same. They cut the "Y" out and ran 2 pipes togeather side by side following the same path as the original as there is only the one heat shield and welded the two Flow Master 50's edge ways up so they would both be under the heat shield. I elected to port them out the side as the fuel tank is obstructing the passenger side of the rear of the truck but they could have made a crossover near the rear to port them out the back on each side. I hope that helps. Jim [/QUOTE]
