They are the same. one side has a gasket fladge thing that slides up into it, but pull that and they are ALL the same!

 

so if i were to buy pipes that were made to hook up to 5.3 manifolds.. I would have to modify one of the down pipes where it attachs to the manifold?

 

I remember that creederado swapped a 6.0 exhaust on to his old GMC and he had to get a manifold also since the one side has a bigger collector. They will bolt to the head the same, but differently to the exhaust front pipes/y-pipe.

 

There is a ball gasket on the passanger side manifold on the 4.8 5.3s the 6.0 did not have this gasket, but it is removable. I have both 6.0 and 5.3 exhaust manifolds THEY ARE THE SAME.

 

Soooo.... they are the same but different? What are you trying to say Wilde??

 

No, I'm going to disagree. I will go outside and get pics tonight.

 

So what you are saying is that if I had a 6.0 and bought a system that was designed to bolt up to a 5.3/4.8 manifold I could buy this ball gasket and be good to go?

 

Well I have a set of 5.3L off that I could do a photo shoot of... I want to know also. I do know there is a steel ring in the 5.3L system. Think passenger side.

 

Fine be that way, It wont be the first time I'm wrong.....

 

Shut up, YOU! lol

5.3 manifolds (EGR off of my 00)

6.0 manifolds....


SAME, SAME, SAME.....


If they are different, I must have got luck, because I haven't had to change my exhaust once. I have had a 5.3 switched to a 6.0, then another 5.3 with different manifolds, and now back to a 6.0.......
ASK ME HOW I KNOW THEY ARE ALL THE F-ING SAME!
