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!
