I have a few questions I want to ask about DC Sports Headers. If I get the JDM 4-1 DC Header will it fit and align with my stock exhaust system on my 97 2dr. RS/LS and does the header come with an O2 sensor bung on the header? If I get the 4-1 or 4-2-1 DC Header for my 97 2dr. RS/LS would there be O2 bungs already on them or do they only put O2 bungs on 4-2-1 2-piece designs? Everyone has been telling me to get the JDM DC 4-1 Header but I am kind of unsure because of the clearence since iit has a 2.5" collector and it sits awfuly low, I was just thinking of getting a regular DC Sports 4-1 one piece or 4-2-1 2 piece since it doesn't sit as low, and has a lot of ground clearence eventhough it only has a 2.25" collector, I don't know know which route to go. I want to build my Integra for Street & Sport, not Drag or Race. Please help, thanks.

I think they all come with 02 sensors,but you can always check in their website.

 

the ground clearance is what steered me away from the jdm dc 4-1. it wasn't worth it to spend money on a header that could potentially be dented and ripped open. nearly everyone i've seen with this header have damaged it in some way, although i've read of a couple people who have never had problems with it. if your car is lowered, i'd probably recommend staying away from it just so you don't have to worry about it in the future. btw, the usdm dc headers have 2.0" collectors so they will bolt up to your stock cat, whereas the jdm dc 4-1 would require a new cat.

 

Thanks for the replies and the corection on the collector size for USDM header.

if you plan on going all motor go with the 4-1 headers.
if you plan on going nitrious go with the 4-2-1 headers.

Thats why theres a thing called Skid plate to prevent denting ur jdm itr header coz it sits low than regular ones. but its true if u get a jdm itr ones u have to get a new cat too with 2.5" inlet.

 

Also remember that generally, a 4-1 header will make it's power high in the rev range, and you may lose some torque lower down, whereas a 4-2-1 will make more midrange power usually without any torque loss down low.
