Are you looking for a TRUE 3" O2 Housing / Downpipe Configuration?
Well its just not possible with the factory O2 housing and downpipe configuration!
Check out the image below of a very popular external dump O2 housing that has a 1/2" of material blocking exhaust flow at the outlet flange! We were very surprised to see this after hearing the reviews of this O2 housing, but we then realized that it can't be helped if you retain the stock mating location to the downpipe as the bend is too tight!
So what are your options? Why not eliminate the O2 housing altogether! Click on the image below of our full 3" O2 eliminator downpipe for more information on the only option on the market that is truly 3" all the way through!

Looks great and functional, but I think it would have been better if it split somewhere before the oil pan. Because if you ever have to remove your down pipe, the whole turbo has to come off and thats pretty expensive. I already had that problem so i just went with a regular O2. Thats just my opinion.

MAP has mentioned in other threads they are willing to put in a V-band connection if the customer so desires. I will say though, there is no need to remove the turbo to install/remove this o2 elim downpipe. My friend bought one for his car and the install went a lot smoother than I expected. We didn't have to remove anything other than what we were replacing; the exhaust manifold and turbo (including turbine housing) remained on the car untouched.

Thanks for the link sir! For less than $100 more than our competition's O2 housing alone (with the above flow restriction) you can have one of these bad boys!
wow these look real good. my only concern is that the factory O2 has a tab to help support the turbo/manifold weight. is there a tab on this piece & if not does that mean the exhaust manifold bolts are under more pressure since nothing is supporting it from underneath?

I'll see if I can get some pictures up for you sir! In regards to the missing tab we have yet to find any adverse affects from the removal of this, whether it be our own product or other options on the market
