I did i quick search...didnt find exactly what i was looking for so ill just ask it here... What would I have to remove to install one piece 4 to 1 headers on a DA? Is it just Radiator and what else?

depending on the header you dont need to mess with the xmember that much.. i have the jdm 4-1 itr header, and i installed it all normal, but they touched just barely, so i just bent down the xmember a little around where the pipes go, works well

bend=hack haha

i guess a litle working with heat and a hammers will do
but ground clearance sucks

i have 4-2-1 and that **** is dented already

 

Well how much do i have to bend the crossmember? how many inches??? and with what do i bend it ?

BFH

you have to beat the crossmember until the header fits....theres no set number of inches you need.....just hit till it fits

 

I just cut about 1 1/2 inches into my crossmember(basicly just the flange). Then i dropped the crossmember down, installed the header and bolted the crossmember back up.

 

ok so jdm itr headers will fit on a da with slight fab work to the x memeber? if i am getting this right then wouldnt a after market itr header work to, lets say from GREDDY? cuz i cant seem to find a damn 4-1 header for my da only 4-2-1

 

I have a megan 4-1 on my DA
