Phase 2 (Received my headers....now what?)

I got my Obx ceramic headers in the mail the other day

http://www.2kracing.com/product_info.php/products_id/1881

but before i go out and purchase the rest of my exhaust system, i want to make sure i'm buying the right thing from the experts (you guys ) ok....my question is...what's the max i can go with the rest of my exhaust system for max performance knowing that turbo will not be in the plans in the future?

go wit watever the size of that header is, no point of getting anything larger than the downpipe size...2-2.25 the most....unless you plan to do some more work to the engine...

stupid question.....what IS the size are my headers?...i can't find the size of these anywhere...can anybody help me find the size of these?...thanks!!

that website dun tell you much bout it, cept the brand and the price....use the ruler and see how many inches it is

It doesnt really matter what the size of the header are, it depends on the size of your catylic convertor. My OBX headers hooked directly up the my catylic convertor and then your exhaust system follows so really it depends on whether or not you are keeping your stock catilyc convertor. If you are, then look for an exhaust that says it is a direct replacement or will bolt right up without doing anything. Headers--->Catylic Convertor--->exhaust system

oh ok...a buddy of mine's has a magnaflow cat for sale still in box (cause he got rid of his honda) ...it states that it's direct fit, but it's only 2" .....will that downgrade my performance and produce a farty sound?....cause that's what i DON'T want

If its direct fit then it should work fine. Don;t know how big the stock one is though. The catylic convertor can be a bottleneck but I chose to leave mine stock...oh well. lol Anyways, the farty sound is based on the muffler and exhaust that you have. Though im sure someone on here will provide a more in depth answer. I would try looking online or calling honda and finding out the specs on everything before you buy the cat.

i appreciate your help man!....i just found out that my headers are 2.25 so i actually went out online already and purchased a 2.25 magnaflow cat....the muffler itself is also a magnaflow...so i'm hoping this whole application'll (2.25 obx ceramic headers, magnaflow cat, and muffler) give me the performance, and sound that i'll like...

BostonPuppyDawg, let me know how your new OBX's hook up. I'm getting ready to get some for my 95 EX, but they will be ss.
Thanks!

once i get them installed i'll give the crew a few review of the power gains, performance, and sounds of a (2.25) obx ceramic headers, magnaflow cat, and magnaflow muffler.

Sounds like its working out well! I think it will sound pretty good....if I could go back I probably would have went with the Magnaflow exhaust as I have heard them and they sound really nice. Oh well.....Maybe my exhaust will get louder on its own. Anyways, as for Slusher I did the cat back and header install and def. noticed a difference. I mean, it wasnt like I was in a Viper but you can tell it freed up a couple of hp. The headers are really nice quality, the welds are good and the thickness of the steel is nice to. Its one of those time whens you expect something of cheaper quality and get surprised that there is a company that makes quality thins for less

Oh yeah, and to reassure you like 95SiR said the 2.25 inch exhaust is about the maximum you can go before your performance actually starts to go down. The only time you need something bigger is if you plan to turbo.

Thanks 19Aaccord97 for the info. I have started hosing down all the nuts and bolts with liquid wrench now and picked up an O2 sensor socket too. I have a lot of other misc. tools and what not but is there going to be anything else special that I should get to do the install? I just don't want to get things apart and then have to back track the whole process. BostonPuppydawg, is the header on? Let us know how it goes.
Thanks

Nope sounds like you have pretty much everything, just make sure you get ALL of the bolts and nuts especially underneath the car near the catylic convertor where the bolts will probably be the toughest to get off. They might also break, so be prepared if you have to go buy a couple more. Be sure to spray the o2 sensor as well. Note that when I got my headers installed, the o2 sensor would not come out and I had to buy another o2 sensor which was around $150 at it wasnt even from the factory, just a precaution. Are you just installing headers or an exhaust too?

Glad to hear the exhaust comes out pretty easy. Did you remove the heat sheild on the manifold to soak those studs? I have yet to do that. What is the best process for removing the old exhaust, start at the cat and move forward? Just looking to keep the whole process moving smoothly. I appreciate your experience with this.

Yeah, I removed the heat shield as it allows you to spray all the studs. The heat shield comes off, it just takes a little moving around b/c the hoses are in the way. You've got it, starting at the back is the easiest but depending on how rusted or "frozen" the bolts are you may need a torch to cut them off. My best advice is to soak every bolt as much as you can at least 2 weeks prior to removing everything. Liquid Wrench will also smoke, I had little pools of it on my manifold and after driving I bagan seeing smoke coming out from under the hood but it was just the burning of Liquid Wrench, just try to wipe the excess off. If you cut the bolts off you will need new ones, and examine your old exhaust rubber hangers to see whether you need new ones or not. I replaced two just because and they cost about $3 each. I would highly recomend having a friend or two help you and planning on taking at least a day in case you run into any unexpected problems. Plus you can use their car if you need to run somewhere and getany parts just buy em' lunch. haha

Thanks for the tips. I won't get my header for a while, slow shipping, but it will give me plenty of time to let her soak.
Thanks again!

No problem at all, glad to help. Good luck with everything too! Also try going on cardomain.com and searching for Accords and see what they've done or wished they would have done, maybe someone will have posted something useful. if not, at least you'll see a bunch of cool Accords!

Cool, I'll check it out! Thanks again.

Anytime

I've recieved my headers and I have been soaking the bolts and stuff for a while now (few more days to go before I think that they are ready) but my obx ss headers came with a gasket for the head but no gasket for where the head pipe meets the cat. Is this normal? Is there suppose to be a gasket in there? Once again, I would hate to get it apart and need something.
Thanks.
P.S.-OBX SS headers look great! Really amazed by by the quality of material and welds. I have yet to put them on but I'm pretty sure everything is going to be great.

Yeah, there should be 3 gaskets. Def. do not use your old one as it may cause a leak. I would call OBX and ask them to send it, but if you dont want to wait then head to your AutoZone or other store and get the gasket. Because the Header fits the stock cat then the gasket should be the same. Or bring the downpipe in with you to make sure. Sorry to hear that though. And yes OBX surprised me to! Let us know how the install went. What year of Accord is this for again?

Thanks for the info again. Yeah it came with two gaskets, head and where header meets head pipe, but nothing for the cat. Thanks for saving me a headache! I have a 95 EX automatic.

No problem at all! Hope it all works out!
