Are the headers compatible?

[chunkmunk]

I just picked up a 1989 Civic DX sedan (20k original miles, yeah!!!) and am wondering if I can use an old DC header from my 1994 Civic EX. Will it bolt on directly? Also, the same question for some ground controls I have? I'm trying to squeeze out as many HP as I can from this automatic. Any advice will be greatly appreciated. Thanks!

yeah it will bolt up to the motor fine, but im not sure if the collector will bolt up to your exhaust though

the ground controls should work too..
