Hi Folks,

I'm looking at the HKS sports cat down pipes.

Does anyone know which option I should go for 33005-AF004 or 33005-AF001.

I notice the dates for each item 04/06-07/06 and 02/11-04/05 respectively.

The car is a 2004 JDM STI, I don't know the exact month of build, is there anyway I can verify this?

Thanks in advance,
Neil

 

I may have answered this myself, anyone more knowledgeable, please do correct me...


The link below details the part a little more. They identify the applied model E, F and G.

From looking at my shortened JDM VIN plate, my Applied model is GDBE***. So I believe the later model codes apply .
