He said he had them on his 2009 Ram, and he just had to use a jig saw to cut a couple of inches off of the rear of the y-pipe assembly and he had to realign the cat back, since these go more to the center of the truck on the angle of the Y. these were $795 shipped, and they do look good, but not as nice or solid feeling as the ARH. Just trying to decide which one to send back, or resale!
I am going to put these side by side and do some picture comparisons later for you guys, and then I can measure out the difference between the measurements on these. Hell, I might be able to set up an OBX kit for the new trucks!!! Wouldn't that be cool?
The problem with using the pre-eagle (08 and earlier) headers on eagle (09+) heads is the exhaust ports are different shapes. The pre-eagle headers will need to be ported or you'll have a big ridge facing the exhaust flow, which can really slow the flow down and you can have worse performance than running the stock log header. Just an FYI. I used pre-eagle headers on eagle heads, they physically fit, but I had to take a ream to the interior to match the ports. It's not perfect, but it definitely does the trick.
