I'm in need of an O2 housing with a 3 inch outlet to match up with my 3 inch downpipe. Can't seem to find the right answer on google or evolutionm.

The only shop I can get any detailed info is from cbrd. They have an O2 housing with downpipe for $900+tax+shipping+waiting a long time for one.

I don't need to buy a new one, just need the O2 housing with a 3 inch outlet.

A few out there don't have specs I'm looking for....Invidia, Megan, Titek.
I've seen Invidia measurements and it's not that close to 3 inches in the outlet.

And no, I don't want O2 dump! Too noisy for me. I have an 02 Dump already. Trying to keep everything quiet as a kitty for the kids and wife.

 

What turbo are you running? 2.5" seems to have plenty of velocity for most DD setups. If it's something that flows as much as an FP Black, or EF4 maybe, but 2.5" does pretty well and for the price of a Megan 02 housing why not consider that option?

 

I'm currently running stock IX turbo. I'll upgrade to either an FP Green or an FP Red. I'm buying everything in pieces. The O2 and the exhaust are the next pieces to the puzzle before I do a tune.


Coming from Honda world and figuring the O2 pipe is restrictive. I have an AMS 3 inch downpipe. Wanted to make sure it mates up 3 inch O2 outlet to 3 inch downpipe inlet. I'm a bit **** about details like that.

 

most of the o2 housings or dumps out there have 2.5 outlets, I wouldn't really worry about it if your planning on upgrading to a fp green or red.

 

Like this??

 

YES! YES! YES! YES!.....YES!!!!!


What brand is that? I don't want Vband...would like it o bolt onto my AMS downpipe.

 

I'll be doing either a green or red. EVO is currently stock right now. I'm just buying pieces this month...the O2 is one of them. Could I get the flanges and get someone locally to build me one with a 3 inch outlet?

 

It was custom made by Toxic Fab. Cost more than CBRD unit and waited 5 months for it. He wouldn't make it stock fitment, not enough length to flow properly.....


The CBRD is V-band as well.....no?

 

Yep CBRD is also V-band but cost way too much as well.


I had a feeling it Toxicfab that made that for you. Was about to post it on facebook and ask him. Dang, would like one built to fit stock somehow.

 

It's not gonna happen......Just not enough room.


How long does CBRD want to make one?
It is a great deal, $900 for O2 housing/ DP combo. I paid more than that for this O2 housing.

 

Not sure how long it takes for CBRD...they may have them in stock and ready to ship. I might as well sell my O2 dump and AMS DP and pay more to get the VBand O2 kit.

 

what a work of art, very nice looking piece

 

Nice o2 housing

 

Thanks, I hope it performs as good as it looks!

 

I did a lot of 02 housing research before narrowing it down to CBRD or Invidia. I ended up with the Invidia, mainly due to the direct fit into my current DP and price. The Invidia is cast with bigger opening into the DP than the generic 02 housings (Megan) and seems to have good flow.

I also looked into many custom tig-welded housings and didn't feel that they do a good job when it comes to flow, especially the 90° turn. While I don't have back to back dynos or evidence of my theory, I drew a quick examples below explaining my opinion.
