Dynotech Supermaxxx

[Reeper27]

Well I am planning on getting a set of headers for my truck, and they are gonna be the Supermaxx headers. What I want to know is if the 5.3s and the 6.0s have the same bolt up pattern, I have looked at the all the headers that Dynatech has for the Silverado, and it just looks like the y pipes are different, the 5.3 has a y-pipe, and the 6.0 is for their true duals to the muffler. Can any help me with this, I want to get the ones for the 6.0 for my 5.3 cause I have true duals and it will make it eaiser to hook them up, and I wont have to have the shop cut the $1200 worth of pipe.
