02 housing question

[odormat000]

are there any o2 housing that have an external dump-tube that bolt up to the stock downpipe? i'm sure there are.
also are there any decent priced ones? or anyone selling one. -thanks

Plenty of cheap ones on ebay if your feeling lucky. Search ive heard some good reviews of them before

We could make something since we make ours in house but to be honest, if you were to upgrade the O2 housing but keep the stock down pipe you would be defeating the purpose.

well i wanna upgrade to the 3inch punishment DP and it has the stock flange when i figure that most external dumo o2 housings have the same size flange as the evo o2 housing, not the 1g or 2g size flange

You need to buy a downpipe with at least a 2.5 inch flange to the o2 housing, then buy a bigger o2 housing. I noticed a very large difference when I added the o2 housing to my 2.5 entry - 3in downpipe. I wouldn't want to keep the stock flange size coming out of the turbo.
