headers

[ferazjaved]

here are a few headers i found on ebay.. are the RRE's really worth it or OBX is iigh? any opinions?

header gains are minimal between the two.. any header is a good header though. just RREs are simple bolt on, where as OBX long tubes your gonna have to weld a bit

you reply exceptionally fast lmao, ill pm you for my next question

[Daxenth]

haha im just on at the right times and no problem man

[b1gkishan]

I'd go with obx! with RRE you will still have the stock y-pipe which is terrible for scavenging as it creates a reverse flow.


**speaking for a gt idk about a gs

[Daxenth]

i always forget your in a GT man. but yeah id go OBX for GT at least. OBX for GS suckkkkkkkk.... RRE is our godsend though

[skysky]

On at the right times? Dax you never get off this site. Haha you must sit there like this waiting for thread updates. But its okay, we like you.

[Daxenth]

lmao. well i wake up to this site. and i go to bed to this site. and usually during the day im at the girls house. so. gotta make up for lost time

I talked to Mike about this once or twice and he was saying how that Y pipe doesn't really affect a whole lot. I guess it's one of those "perfect engineering" things and that even by them making a custom Y pipe that eliminates the crappy looking stock one wouldn't net much gains.

Personally I'd go with the RRE headers due to less modification to make them fit right. I'm not comfortable with extending wires on O2 sensors, welding, and whatever else you need to do for the OBX. I've seen the RRE ones in action and I'll stick with the guys that have been doing Eclipse/Evo parts and performance since the beginning of time. ^^

Of course when it comes down to it, it's all about your budget and how much work you wanna do.

I have the OBX long tubes and love them and I guarantee my Y-pipe works better than anything stock

[joeyb]

long tubes are a little better in my opinion, and required if you ever want to go forced induction. long tubes to a large pipe sounds the best for the v6 in my opinion.

yeah, but did you guys install the headers yourself? what else do i have to buy with the longtubes.. like the o2 sensor wire n stuff... and i'm not that accomplished of a mechanic so ima have to get someone to do it.. what if they dont know how to do that stuff? or will they lol

[joeyb]

^man I say if you read up, study and understand each step, have tools, then you can do the install yourself. it will be at least a few hundred dollars more to have someone install them for you unless you know a mechanic who'll be very nice to you.

there are several how-to's on this site that go over the installation of the long-tubes and what is involved. yes, if you buy the OBX kit then you'll need to extend your o2 sensor wires in some way. that is just about the only other thing you'll need, except maybe getting it welded into the cat-back at the muffler shop. $50, 1 hour worth of work. easy.

[joeyb]

check out this thread - 2nd page, about half-way down. you can see some of what is involved in the install.

Freekers' LongTubes' Thread

[rgv4]

I have the obx headers. Basically all u need is a jack, socket set, wrench set and some wire to extend the o2 sensors. Also heat shrink wrap. After all is done u just take it to a weld shop to weld the test pipe. I believe freeker has a how too thread

Did it all myself and if a mechanic says he doesn't know how to do it ...then never call him a mechanic again. The install was simple...hardest part was getting the factory crap off. O2 extensions...some wire and I would recommend soldering the connections and shrink wrapping to prevent water getting to 'em. You will have to cut a little of the exhaust pipe before the cat and either clamp it to the test pipe or have it welded.

[pdiddy1995]

The OBX headers are simply a less expensive (knock off) of the RIPP longtubes and the comparison between RIPP and RRE headers has been ongoing for a while (litterally years) on this sight. what everyone's pretty much discovered is the longtubes are better for heat scavenging which is great if you're autocrossing or doing laps at the track, but not really needed for DD or occasional racing. As far as the power goes, the longtubes pump out around 5whp more peak power than RRE with a stock y-pipe but the RRE headers put out more midrange power. RRE headers with a custom y-pipe put out the same peak power as the long tubes with no loss to the midrange which has it's benefits.

The important thing is that you modify your car according to your own personal driving style and budget

hey man I am in NJ several times a year - when are you planning on doing the install? maybe I could stay an extra day, help you get started and pointed in the right direction. the toughest part is getting the stock manifolds out. and maybe I could do the soldering for you. let me know, I'll be in NJ/NY in early March for several days.

I HIGHLY recommend you do the motor mount upgrade at the same time.

Custom y-pipe as in "take it to a local shop and have them fab something" or are you talking custom as in "been built, jig in hand and can build more on the fly for stock exhaust set up (like RRE did/does with their dual axle backs)"?

This may seem like a stupid question, but my exhaust is far from stock. Only the stock y-pipe remains. However, it still follows the fitment pattern of the stock exhaust.

So if a quality after market y-pipe exists that simply replaces the stock one, then by all means please share the info.

I dont think there's one out there. I read RRE looked into that and found minimal gains vs. cost... If there were real gains to be had, you'd think RRE would offer one... It would be a piece of cake for them compared to the headers!!!

[BrianJ]

I think the stock y-pipe is fine the way it is...just because it has one bend in it doesn't mean it won't flow...

[pdiddy1995]

Not saying that the stock y-pipe is a seriously weak link, its definitely not, thats why RRE didnt see the need to change it after they made and tested theirs. Just saying that once the stock y-pipe is replaced, any difference in power between the shorties and the long tubes is completely gone. Keep in mind i'm talkin about less than 5whp so most wont notice any difference at all. If you are simply chasing after those higher dyno numbers then every little improvement can, however, make a difference.

There currently is no template for a y-pipe replacement so if you want it you will have to get one made and honestly, the performance difference isn't really worth the price ($100-$300 for less than 5 whp, depending on the shop) but if you're just chasing numbers and money isnt an issue, then you may want to do it.

I'm lookin at getting a custom y-pipe made for my setup simply because i need every single little (or big) increase i can get with my NA setup in order to keep Carl's (horse eater) taillights in view when his twin turbo boost kicks in, and i've been blessed with the fact that money isn't too big of an issue for me.

My best advice, do what you can do and make your car the way YOU want to make it

Making up lies about stock Y pipes makes stock Y pipes all over the country sad :-(

Stock Y pipe:

[deprydation]

I don't get it....but OK.

Are we describing back pressure here?

EDIT:

I'm a stupid. I was looking at it thinking I was all bass ackwards....

Yeah, Mike is right, it flows just fine. I know MitEclipse07 got the custom Y pipe done for like 180 bucks and says he feels a difference in it.

Who knows though. I'm sticking with RRE. They seem to know what's up.

[Chaos]

Really flowing left,right,up,down dosnt matter so long as the pipe is proper sized and mandrel bent with no restrictions, its gonna flow fine. The force behind it its gonn push it the minor "bend" it has to go thru.

[joeyb]

REST DELETED b/c misleading.

............. like I said above, the difference will be minuscule for the majority of drivers. but boy I tell you, the long tubes sure SOUND mean as f*ck.

[BrianJ]

^^^ That MAY be true to some extent, but honestly, I think as long as you are mandrel bent and not crushed that it isn't going to be worth the difference (if any). I mean, you're still going to have to bend the custom y-pipe too...so really, what's the difference?

Also, more flow doesn't always mean more power either...it might be best suited for redline performance...but how often are you at redline? Cut your pipes off a foot from the head, that'll give you little to no restriction...but you're low and mid range power will pay dearly for that...

IDK, I don't think it's worth it...I really don't think you're going to see anything from it...the stock pipe is the proper size and it's mandrel bent...and it's 1 bend...not a whole bunch of twists and turns...and the front portion of the y-pipe you really can't improve upon other than maybe getting rid of the 45...but it's going to have to bend somewhere to clear everything...

I'd like to see what a "custom" y-pipe looks like for this car...it can't look all that different from the stock one...

[BrianJ]

Joey...

What do you mean about "having one blowing back into the other"? It's just a standard "Y" merge...I don't see the difference in this or any other "custom" setup...even the longtubes have a "Y" section where both pipes come together into one...

[joeyb]

keeping this for the info and thread flow - BUT MISLEADING - BRIANJ IS CORRECT. I AM WRONG.






just seems like whatever gains in flow the shorties buy you are gone once they hit that stock y-pipe.

here is the long tube design:


probably not a ton of difference, I'm sure. but again, I sure like the way the long-tubes sound, and I know that I have maximized my exhaust from the head all the way to the muffler. I may be a little prejudice against stock parts and this stock y-pipe in general, tho.

MitEclipse07....

Got any pics bro?

[BrianJ]

^^^ Now that right there drops off RIGHT INTO the other pipe...it doesn't even look like a good transition angle...it looks like it almost 90 degree's into the other pipe! That to me would be restrictive...but that's a bad angle...

And the big advantage to headers of either kind is that you get rid of the cat's in the manifolds...that's your restrictive part...not the "Y" pipe...

I would call that a "T" pipe, which you would think wouldn't flow as good as a "Y".

[joeyb]

if you want to sound beastly like an STi - then long tubes.

[BrianJ]

What are you talking about with "backward blowing"??? On the stock setup, both pipes flow exhaust in the same direction when they meet...never does one pipe blow gases into another pipe in the opposite direction of flow...

[BrianJ]

LOL...you must be...the "front bank" of headers is out of the picture at the TOP of the screen...look at the direction arrows...the front bank blows DOWNWARD in this picture (from top to bottom)...the rear bank is the one with the bend in it...it goes around and MEETS the front exhaust flow IN THE SAME DIRECTION the front exhaust is flowing...never does one send gases into another in different directions...they just meet up, same as your longtubes...

[joeyb]

Ahhhhh..............i seee.

Brianj is right of course.

sorry guys I am a dumbass. looks like the y-pipe flows better then I realized. but still - that backward bend isn't good but probably doesn't even matter.

You're not a dumbass. BrianJ just pwnt you with the force.

not hard for him to do.

Does this now solve everyone's beef with the stock Y pipe?

answered my question.. and i couldnt agree more with the "Pussy Magnet = Stock" lmao
