O2 housing or NOT??

[fastfive0]

Looking into buying a turbo back exhaust and was wondering should I go with the O2 bypass or keep the o2 housing. What are the pro's and con's of each?

go with the o2 dump and then you have no boost creep and an awsome sound compared to some boost creep no sound ??? so its up to you.

What does an O2 housing do? What's it there for? I'm a newbie and have no clue

The O2 housing is just that. It houses the O2 sensor. O2 eliminaters are tubular stainless steel as opposed to the cast iron units on the cars stock. The absolute best way to go in my oppimion is with a full 3" O2 eliminater down pipe, like the one dsm performance sells.

Im confused as to how the o2 eliminator works though.. where do you mount your 1st o2 sensor at then?

They still have a bung to screw in the oxygen sensor. It's just in a pipe rather than a cast piece. You can kinda see it in the bottom picture from the rnrracing website:

That confused me at first. O2 eliminator is a mis-leading name.

By O2 bypass I assume you're talking about an O2 eliminator downpipe. Here's my take:

O2 eliminator downpipe:

pros:

1. flows better than any O2 housing
2. you don't have to take your housing off and get it ported, you take care of all your exhaust upgrades at once.
3. Less chance of boost creep.

cons:
1. More expensive initial cost.
2. Not a ton of place make them so you usually have to buy your whole exhaut from the same place, get flanges welded on to your downpipe to fit specific cat-back brands, or go with slip fit connections (which work fine).

regular downpipe with stock O2 housing:

pros:

1. cheaper initial cost. However you're probably going to have boost creep problems (depending on exhaust diameter, cat, no cat, etc.) or find that you are flow limited depending on how far you go. If you are paying someone else to port the O2 housing, you probably could have bought an O2 eliminator downpipe for the around the same money as regular downpipe + port work.

cons:

1. possibly flow limiting.
2. possible boost creep.
3. see second half of pro #1.

I have an O2 elim dp. with an internal dump. I love it.

that makes sense now.. thanks for clearing that up for me.

Love mine also, ans have never had boost creep

I have or im getting a custom exhaust from the o2 housing back my question is I dont want to have to deal with porting! shoudl I just buy a 02 dump fpr 115.00 shipped and bolt it up? I kinda want the loud sound!.



does the o2 dump make any more hP than a o2 eliminator?

O2 eliminator can either be vented to the atmosphere or routed back into the downpipe.

 

[candela]

The most efficient youll really get without an external gate is to have an o2 eliminator with a dump tube. Extreme turbo's 3" turbo back o2 eliminator has the option for a dump and its only like 15$ more. Its a decently priced exhaust IMO.

I was wondering if you gain more HP when you dump a internal gate rather then recycle the gasses back in?

Sorry for being such a noobie at this but....

i have a ported o2 sensor, and i like it alot better than stock and everything but the problem is i still get boost creep....
i was wondering if a 3" dump tube would just bolt up and be fine, i have the 3" boucher racing downpipe..

and who makes the best dump tube???
ive never heard one before but what kind of noise does it make???

 

[Moorepwr]

I have extremes o2 elimi. down pipe. I love it. Recommend it to anyone wanting to absolutly open up their exhaust.

There is a lot of good information in this thread that I think will answer your question. This Candela guy sounds like he knows what he's talking about.....

thanks I know all of that but do you get more HP from a internally gated dump or recycle that is not in the text that candela wrote

 

[candela]

its all the same.... it just helps with boost creep/control
