DC makes a header for the 84-87 CRX Si. will those fit the DX carbureted engine? The Si and DX have the same head right?

Gasoline Fumes

They will fit, but you need the Si oil pan. It's not the same head, but the exhaust ports are the same.

spdzone

that sucks. too much hassle for me.

thanks

spdzone

ok, nevermind, i'm pretty sure I want to get the header now. I just need to know if the headers will bolt right up to the stock exhaust system with out any cut/weld job. also i don't plan to run a catalytic converter.

thanks for any help.

Gasoline Fumes

I really don't know if it will bolt up to the stock exhaust or not. It might.

It does, and if you really need to get a cat, the stock Si one will work as well.

spdzone

thanks guys, but i have another dilema. I looked under the hood again to see if I needed to do anything else. I noticed that connected to the cat is this silver pipe/egr looking thing that goes to another part off of some vacuum thingy connected to the carb. I hope that makes sense. I need to break out the helms for the correct terminology. If I really need that part then i'm stuck and not going to be able to get the header.

1stGenCRXer

Yeah, that pipe is for the EGR, which means you'll need to make a blanking plate for where it connects to the intake manifold if you plan on getting a header.

spdzone

ok, i'll look into that and make sure it doesn't need that extra air to come throught
thanks
