i remember reading back that there were 2 different DC 4-1 header's. One was a regular 4-1 and the other was a JDM 4-1. I was wondering if anyone can tell me the differences between them both or it doesnt really matter? Shopping around and dont really wanna get something i didnt want.

 

You have the regular DC 4-1 header which has a 2" collector and the JDM DC 4-1 header has a 2.5" collector.

 

thats kinda interesting

 

thanks, appreciate the help

 

the jdm 4-1 sits lower below the oil pan than the the usdm, so its more susceptible to scraping/denting

I think this is correct, but the USDM 4-1 also hangs really low. So don't buy the USDM just because you think you won't scrape - I put 2 craters in mine quite easily when I was on Neuspeed Race. If I were you, and this is definitely the brand you wanted to go with (over Comptech, AN-R, Bisi, Hytech, etc) I would get the JDM one and get a high flow cat custom made to mate with your piping due to the different length of the JDM.
