Yeah, i just found out about the cat-back system for the the ex,lx,dx civics....i was wondering if anyone tried one out yet??

also how much HP does a cat back system add??

 

I know alot of people used it on there rsx's and it got good reviews from the people i heard it on a rsx type-s before and it had a nice smooth rumble prob not going to add much without a race header or hondata reflash.

 

7-10hp.........depends

 

where can i find racing headers for the ex??? or hondata relfash??

 

Try dc sports headers or wait for comptech to drop there headers on the market soon i heard people are not happy with dc sports quality lately as far hondata just go to there website.

 

aem's website rite??

 

DC race header = Piece of ****.

Just wait until Comptech releases their header. You can go to http://www.hondata.com to find a retailer near you that will do the Hondata reflash on your ECU.

 

....so far i cant even find a reflash on their site for the EX...also...where are you reading the DC race header info.?

 

You more than likely won't find a reflash for the Non-Si, Ever.

As for the race header, it is only available for the Si as of now. I can get one for my '05 EX. But seeing as you guys TECHNICALLY don't have a header, it sucks to be you. The "manifold" is integrated with the cylinder head. Your bolt on exhaust parts start at the B-Pipe/cat converter right there at the head. So you probably wont ever be able to by a header for it. Unless somebody comes out with a new head that eliminates the integrated head/manifold piece.

 

deng......i thought they were makin headers for the ex..and other models...but are they makina dc cat back system?

Yes, I am sure you could find a DCSports cat-back. But as for the HEADER, I am sure tha no aftermarket compant will come out with a header for the EX and lower. Simply because the head has an integrated exhaust manifold. Notice the picturo below...............



Unless acompany comes out with a cylinder head that wuill accomidate an aftermarket manifold, you ex guys are out of luck for a header on the EX.

That's ridiculous, just wait a few years. That's like saying no one will ever have a fast d-series.

Also, a cat-less "downpipe" of sorts would be beneficial for the R-series, and similar to a header, it just wouldn't look like one.

 

Header? bah, turbo!

 

do you think the EX can get up to 200HP?

Can you say engine swap?

Depends if you are driving auto or manual. Your answer should be manual. To answer your question, a number of upgrades would need to be made. I think the only way you can get close is a turbo/supercharger and you will still need more performance parts. In doing that, there are so many factors to look at. An engine management system would help tremendously as well.

For the money you will spend, you should just have bought the Si.

Yes, can you make 200 on yours reasonably....no, unless you spray it.

 

I have an EX and i just put a cold air intake in it, (blue to match the inside) but once i get my next paycheck im gettin the MagnaFlow exhaust, cause that the only real thing they have for the EX rite now, and it sucks that we EX people will prob. never have headers for our cars. But im happy for now with my cold air

 

Got any clips of that magnaflow? Ive come into a large pile of money lately and am thinking about it =P

 

any other cat back systems out there?

 

Yea greddy evo 2, Dc sports, tanabe.

 

FYI, for you Si owners, Magnaflow just came out with the Si Catback.

If you love Magnaflow, then there you go. They have a sound clip/video up for idle/rev and drive by. No Dyno yet though...

 

They Probably will never have a true header for the R18a, but they do have a stainless downpipe which replaces the cat (for $400).

 

Doesn't the magnaflow have very poor fitment? I heard that some customizing was needed and the hangers don't exactly line up to the stock locations.
