Header question
Trending Topics
All the JDM 4-2-1 headers (Type One, Spoon, Toda and Jun) have 45mm primaries and 50mm secondaries. The Mugen 4-1 has 45mm primaries. The DC JDM has 1.75" Primaries. The ITR JDM has 43mm primaries.
JUN Header = Designed for JUN Cams
I have a JUN Header and my Stage III Head Package and ECU are going in next week. I have seen many Stage III w/ JUN Header setups. Works great!

Because it was a stock R they used to test the headers on
I'd get either SMSP or Toda.
I didn't think much of the Toda header until I saw Vegeta gained almost 20hp in the midrange over his DC JDM after tuning.
