Heres what you need:

- Megan header for and 96-00 EX
- Cat from 96-00 EX
- Either a 96-00 EX sedan cat-back exhaust or custom piping either 2.25 or 2.5 w/ a Magnaflow resonator and muffler (there's more options, but Magnaflow is cheap and sounds good)
- Password JDM o2 extension: http://passwordjdm.com/PasswordJDM-O...t-P1767C0.aspx

It will line up perfect, you won't have to splice any wires, you'll stay emissions safe, and it will sound good.

Thanks for all the help guys. The O2 sensor problem was really the only issue I had and now that that has been fixed I just need to decide on a cat back then horde enough money to do it.

Again thanks, I have asked on a few other forums and usually it was a case of "Do an engine swap" or "just get headers and run a straight pipe"

I'll try and post pics and/or video when I get around to this project.


*UPDATE*

So after Discussing with some friends and such it is down to either a Megan or an RS*R EX-Mag cat back.

Megan
I like the sound of the Megan better in the higher RPMs, but its idle sound and that ugly 4" tip can are not so nice. But its cheap and that's a real good selling point.

RS*R Ex-Mag
This exhaust is nice and subtle and not overly loud at idle however when you stomp on it it opens up. However this part is more expensive. Also, every web page with an RS&R EX-Mag has it list for 96-00 EX coupe only. Now I know the 4dr and 2dr have the same size body so I take it this will fit my 4dr and they just have some odd wording in there. if this can be cleared up that would be great.

haha those are two very different prices. Megan will be good, and i think Forty04 used the Megan Drift Spec for both N/A and boosted, which leaves your options open for the future. The Ex-Mag is truly one of the best sounding catbacks i have ever heard. If you have the money GET IT. You won't be disappointed, and also:

they sell the same cat-back for 96-00 2 and 4 door. I think it should fit, probably just worded weird like you said.

Well my exhaust had a rattle there for a while. Turns out it was where the downpipe attacked to the cat-back. Well I can say that the rattle is gone, as they flange broke and the pipes are separated.

here are two videos of what my car sound like right now

Normal shifting
power shifting

And since I have to get an emission test done I have only afew options.

Option 1) Replace downpipe. I need to acquire and replace exhaust pipe A in the picture below. This can TECHNICALLY be the cheapest. But if I run into problems, I may end up spending a lot more.

Option 2) Convert to d16y8 style exhaust now, and hope I don't get any CELs


Option 3) since number 2 and potentially number 1 can run problems and cost upwards of 1000, I buy my neighbors Nissan Atima he is selling for 1k, park civic at a buddies and turn it into a project car.



Advice? opinions? all welcome.

mmm, if you're really worried about it, chop off the flanges and have the header and catback welded together. Yeah, its kinda permanent, but are you really swapping exhaust/headers everyday?

have you tried taking it to an exhaust shop? similar thing happen to me a while back and they just welded in a flex pipe into the down pipe and charged me $90

+1 for flexpipe
