so will catted or high flow catted headers be the same?

Mine are high flow catted only because I have a yearly visual inspections in my state. From what I understand uncatted makes a difference at above 800-900 hp.

Not sure about any difference in the sound.

Yeah you have to lift the engine to put them on.


I bought my headers from Shelby.


The one and only reason I bought from them was for the GT500 engraving. Not surprisingly the headers I received didn't have that engraving. I guess it was my fault for once again trusting Shelby to deliver on what they advertise.
