Finally got my ARH headers installed on my 1999, 2500 4X4. Have the same as many others have had to say about these headers, amazing attention to detail on design and quality. Wish there was a dyno in my area to measure the increase of power but am happy with the difference felt in driving. Only warning i can give is that the connecting pipes are a lot different than what comes on the 2500 series, nothing a sawzall and a welder can't fix.

 

Sweet, another happy customer

 

Congrats on the new headers! i felts some nice gains on my truck after i put the long tubes on and got it tuned, it made my truck run lean after the header install and it would ping alittle when it was hot out, so had it tuned and holly ****! it felt nice after!

Throw some pics up of the new headers.

 

Wish i could do the picture thing, but i'm not picture post literate. I forgot to mention i replaced some mid lenght 1 5/8" primaries with the ARH and still got significant gains, so i can only imagine a greater improvement going from stock manifolds to these.
