Whats a good Header?
I'd like to take out my stock exhaust manifolds and replace them with some nice headers. I have a Stock 5.0 TPI motor and have a cat for emissions, so the Headers that I need will have to have air tubes for the cat.
What brand makes a Good Header with the air tubes to keep it stock for emissions?

Re: Whats a good Header?
I have the Borla Cat-back exhaust on there now, so I dont know if I have to change the Y-pipe or those Headers will fit the Y-pipe thats on there.

Re: Whats a good Header?
Ya same here. Ceramic coated, I would shoot I'm a message and have him quote you. They aren't cheap but if you do the comparisons and research they look to be one of the best.

Re: Whats a good Header?
When you order them he will ask you what heads you have. I think he tweaks a tube here or there, but he can make them fit straight, angle plug, and L98 angle plug.
