Worth installing 02 housing?

As for the O2 Housing cracking, the Helix I have is some heavy gauge stuff, I mean really thick. I really think my turbo will die before the heat cycling will be enough to stress the housing to the point of cracking.

One has already cracked. I think alot of the people who put it in have a placebo effect. They think it does a huge difference. You'll probably notice better spool up and thats about it. Its a worthless mod as far as money is concerned.

honestly, I really havent seen a graph with a comparo so whos to say but all the posts Ive seen with people that have them said they made gains and 1 post(i cant seem to find it...go figure
)said that it made about 10whp but he didnt have a dyno graph

I have chosen to comment on the fitment and quality of the piece, nothing more.
Rest assured, if something ever does go wrong, I will snap some pics and post away.
Another thing, most people don't purchase this mod to work alone, it is part of the whole exhaust system, so when combined with a dp, high flow cat (or test pipe) and a cat back, all the exhaust pieces will benifit and work in harmony. That is the purpose of all mods, no?

Here is a ported and ceramic coated factory O2 housing for you to see:

Go with a ported stocker. Not only will it last but it will also support the weight of the turbo.

That doesn't make too much sense, does it? I never said it hit full boost, it simply spools noticably faster in my opinion. Good catch, though! Oh, and I'm also running mine without the heat shield. I couldn't get it to fit. I've talked to several mechanics who don't believe it will be a problem.
