05 Doug Thorley Headers- 04 vs 05?? (1 Viewer)

[bird67]

I am trying to procure a set of DT headers for my 05.....and for whatever reason there are (2) different part numbers:

1 PN for 1998~2004 and a second PN for 2005~2008

What changed from 04 to 05 to require a different part number and why is the change point at 2005 when 04 and 05 are identical (I think)

the only difference i can think of is the SAI / VVTI ... otherwise all the 2uzs are the same

I don't know what their deal is either, it's off by one year (vvti was 06, not 05), all I can think of is that somewhere in there it's build date not model year or something. I have an 05 and have the "98-04" headers on, as i don't have VVTI and it's all good.

Website/manufacturer error in years. There's no 08 100 series. Guessing they meant 98-05 and 06-07.

Apparently some late 05’s had SAIS.

I asked DT this same question when I was ordering headers for my 2005. As long as you don't have the VVTi variant of the engine, you're fine with the '98-04' version that DT lists.
