I have read that the stock 3.0 headers fit on the 3.5 heads, if this is true will the cattman headers for the 3.0 also fit on the 3.5? I know this is probably a dumb question, but im kinda dumb so i thought I'd ask

 

The Cattman headers (gen I) are made to fit the 4th gen....

We did some custom fit work to get them on the 2002+.

 

the work you guys have done, is it minor or close to major?? because if it isn't complicated, i'll order them and have them ready when i do the swap

 

Ok so my next question is if i swapped to the 3.5 would I still be able to use the headers on my 4th gen

 

If this had not been answered before I would answer it, but it has so I wont. 3 letters for the answer....



No, it's never been done, not even by the fastest N/A 4.5 gen 5MT, and 2 others.

 

Luke, use the force!

If A=B and B=C, then A=C.

 

Ok thank you. Just don't want to be getting headers that ill have to replace anyway when I do the 3.5 swap down the road.

 

All I had to do on mine was extend the O2 sensor wires and plug up the EGR fitting.

 

Pretty simple actually.
