The exhaust manifolds on your 4.7 are more efficient than most, what are you trying to do ? Are you more interested in dress up/noise or do you want to build power ? I'm not trying to slam you, that's just not where the power is for your truck.

Aftermarket headers for the 4.7 really aren't worth it, but the best probably are JBA's

By all means, do other mods first and headers last, if want to go that far. The factory 4.7 exhaust manifolds flow within 2 per cent of headers, hardly worth the trouble or expense.

Seriously though, when the Magnums first appeared there were no headers available that'd outflow the manifolds. After less than 2 years, the OEM's got a slightly smaller inside diameter, which cut about 10hp, and the header guys stepped up with newly improved header designs. Give 'em time.

There was a story on the web a couple of years ago (allpar or similar) talking about the D-C exhaust specialist engineer. His job was to design the 4.7 exhaust. They made a direct comparison of the production exhaust to headers, and came up with a 2% efficiency loss on the stock manifolds. Given that the engineer had all of D-C's resources at hand, I agree that the aftermarket header manufacturers have a lot of homework to do first, before marketing 4.7 headers.

I think properly built long tube headers are the best overall solution for the 4.7L :) But I might be biased...

You're probably right, but isn't the only way to get them to fabricate them yourself ?

Demon's got a potential design in the works. R&D is patience though so we'll wait. I'd return the Gibson's and wait for Demon's personally.
