What year of 800 header pipe will fit mt 04 600?

 

I'm guessing that you want the 08 800 HO header. That is what I have on my 05 700efi.

 

Do you mean the manifold or the U-shaped pipe behind it etc? If it's the manifold, is there a difference in years? My 07 800 cracked the manifold and I had to replace it, just wondering if the part was updated or anything.

 

The 800 header (y pipe) put on the 600 & the 700 is supposed to be a performance mod. Not sure if different years are different .

 

te pipe opening is bigger lettingmore air flow is why they starter using them as well as the air inlet tube i do belave. the 05-06' are 1 pn# the 07' is a pn# and the 08-09 is a totally differnt pn# from the rest?
