does anyone know what type of set up and the size of the factory factory exhaust on these trucks? is it similar to the 2500HD trucks?

Dr_goodwrench66 03-22-2007, 10:28 PM The exhaust is the same size as the 1/2 tons. Only the HD's get the 3-1/2"... diesel625 03-22-2007, 10:41 PM the reason i am asking is because i was asked to install an aftermarket muffler on the truck, but i did not look under it. do they have duals into one pipe out of the muffler, a single pipe, or duals with a y-pipe after muffler? and what size is the piping? DieHardChevyMan 03-23-2007, 10:42 AM I have a 2001 1500HD and it is different from the 2500HD's. I have 2 pipes going in and 1 going out. The 2500HD has 1 pipe going in and 1 going out.
