I currently have a 99-00 Civic Si and want to swap my DC headers and Magnaflow exhaust to stock. Does anyone know if any of the stock headers and exhaust from DX EX or HX fit into my Si? I want to pull them from a junkyard but not sure if they will fit.

 

Header from another model will not fit, the catback exhaust system from any 96-00 sedan or coupe will fit. I believe the si model had larger diameter piping, I would get on Facebook to see if anyone would tade you

 

if its a dseries engine it will fit

 

The D-series will fit, but the exhaust manifold won't attach to your B-series head.

Curious. Why do you want stock?

 

Currently, USDM '99-00 Si's (EM1) are bringing more money on the used market when they are STOCK instead of modified... even gently and tastefully.

 

You will need a stock '99-'00 Si header.

 

you guys also need to think about the si in canada, he could be located there as well. the canadian si has a d16y8.

 

I’m located in USA, B16A2

Guess I have to look for someone parting an EM1 out.

 

than its not a dseries

 

*then

Have you ever found a solution for this?
I have a 1999 Honda Civic SiR (Canada) with a B16A2 motor and I am trying to return it to stock as well. I would love to find out what happened in your application.

 

D series headers do not fit b series. You have to get your engine stock headers.
