I'm trying to decide whether or not to get the DC JDM 4-1 ceramic header. I have always heard that it gives great top-end power but low-mid ranger power suffers. Now I'm not sure if this is completely true as I haven't seen the dynos to prove it.

My GSR is my daily driver so I would not like to lose any low-mid range power. Should I go with a 4-2-1 or DC JDM 4-1 or does it even matter? Anyone have dynoes or anything with the DC JDM 4-1 header or even a 4-2-1.

Thanks

 

The dyno charts I've seen of the DC JDM 4-1 have shown gains across the entire RPM curve, with no losses over the stock piece.

 

from what i know of.. 4-2-1 = top-end power & 4-1 = botton-end power.

just from what i've heard.. i have a 4-2-1 greddy ss.. and i luv it.

 

i think the jdm Apexi header is perfect for you!

The JDM DC header has a 2.5" collector which helps exhaust flow.

Typically, 4-2-1 is for mid-range and 4-1 is for top-end. This is not the case for higher end $500+ header such as Hytech, Comptech, etc. which have the best of both worlds.

would it matter if I'm going to stay with the stock exhaust system?
