Should work though, I've heard members getting 5.4 headers for their 4.6. Problem is the 4.6 being shorter, headers might be close to the heat shield and stuff like that. I dunno, should be fine or at least able to be "adjusted" to fit.......

there was a member here that put the obx's on his 4.6. To me it seamed more hassle than what it was worth. I believe his name was jackal.

I have OBX long tubes on my truck. The OBX cats will make you throw codes, trust me I know. Also don't use Ford gaskets, the Ford manifold flanges are a different ID shape as the flange of the OBX's and they will not seal properly and leak, again trust me I know. The OBX gaskets work fine.

That is the correct set of headers for a 07 HD. Just pick what option(s) you want.
I run OBX catless in AZ and use Gotts O2 mod for emissions. No check engine light so it passes the test easily.
