I heard today from a friend that Stillen makes the header piece for the maxima. The part i am talkin about is the three piece header connected to engine, thats the piece that y-pipr bolts on to. So if any one has heard of this or this is totally a oblivous post it so i can know.

 

I believe option 2 would be the correct answer as of now.

 

I posted a thread asking about this piece. It would be the most efficient exhaust manifold. When I had my old prelude header replaced, the factory one was really crimped with small tubes. I mean stillen makes one like that for the Sentras. Or am I just missing something?
