Here's a nice pic of them installed on an Altima:




I dont't see any center crossmember...

 

Thats a strange install though. I mean the cat's welded to the y-pipe.....

 

No o2 sensor bungs for the extra ones the 5.5g has ... Extended to after the cat like ours.

 

those arnt stainless either.

 

well they dont clear crossmember..............

 

I can't imagine why... Were you serious about trying to make them fit?

 

I will make em fit with some mods.......crossmember mocs that is..

 

so would these fit a 3.0 5th Gen?

 

No they will NOT fit a maxima only a altima......They are stainless though..

 

So you are gonna force them to work?

 

actually it came with 4 o2 bungs not 3 one in each header and two in test pipe

 

man i want to order these altima headers so bad just to try to make them fit. can you imagine $150 headers ahhh thats all i think about... lol. ok does anyone know if tilley was even putting them on a maxima or were they going on an altima? surely if he can do it i can do it....... haha just playin

 

look at post #49 and they will work if you design a 100% diff crossmemer .

 

If these somehow magically fit the 3.5l maxima's then they should fit the vq30de-k. Maybe with cutting the y-pipe and placing it at a different angle it would fit.

 

The only thing I can think of is either redoing the "y" part of the headers, or designing a different crossmember, which would IMO be wayyyyyy to much work just for headers, and for that price, you can get Cattman ones......
