are all aftermarket o2 housings basicly the same or is there a significant difference between the brands? dont want any dumps. any inputs would be great thanks

 

most important thing IMHO is the diameter of the housing after that you are paying for the name. I have a no name one i got from a friend that works great and i could feel the turbo spool a lot faster.

 

by diameter do you mean the outlet that bolts to the down pipe?

 

No that should be 3", i was referring to the ID of o2 housing it self.
Just curious why not get the EPM V2 open dump?

 

i have one, and well it dosent clear my licp that good and i want to put my stock undertray back on without it being melted. iv seen a better dump made be jm fab or whatever they are called but i wont spend $450+ on a o2 housing.

 

I went with the Megan 02 housing just because I'm cheap. I got it from CVR motorsports on evo M for a steal. I could certainly feel a difference over stock, if you wanted to spend more and get a little better flow you could check out the one that invidia makes. GL

 

btw i was told i have a version 2 of the epm dump and im using it with nisei licp and it dont clear that good

 

I want the Maperformance one with the Tial WG built in! They are baller$$$$$

 

Megan and Titek are nice. Most BAY pieces are fine too.

Just have to make sure the inside hole transitions nicely and is not too small or you'll get some creep.

 

just to be clear all open dump tubes have to have the undertray modified correct>?

 

yes

^^agreed with that, I'm running a JMF internal O2 housing and I noticed improvement over stock

 

ebay all the way its just piping i would drive a honda before i spent 400 on a o2 housing

 

You have to be CAREFUL . You need a O2 housing that will bolt to your downpipe. I have an Invidia that I cant use because the outlet is too big for a Buschur down pipe. Just do research and ask the vendor if it will fit your downpipe. Got an Invidia forsale cheap lol
