I have seen that there is a Greddy Stainless 4-2-1 1pc header for sale, and it's for the 99-01 Civic Si.

Now I am going to get the JDM B16A SiR-II engine for my Civic Cx, and I wonder if this header is compatible with this JDM B16A engine as well?!

I checked Greddy website, and they do not have a listing for the Delsol VTEC. Then, I checked DC Sports, and they listed the same part number of header for both the 94-97 Delsol and 99-01 Si. That's why I am confused.

Anyone can enlighten me on this one? Thanks for any info.

 

yes, the exhaust ports on all b series are the same specs.....the only difference between them relies on the deck height

in other words, you'll be ok, it'll bolt right up

 

Thanks! So either 4-2-1 and 4-1 will fit correct?

Hmmm, gotta choose between Ceramic and S.S....any suggestion besides the look?

 

i would personally choose ceramic....simply becuase of the price difference

i would also choose the 4-1 design rather than a 4-2-1

 

4-1 is better @ high end correct, while 4-2-1 flows better @ mid-range?

Which is gonna rust first? Ceramic or SS?

Header is something I am not too sure about...thanks!
