Would you further explain that? From my understand, every o2 housing out there has a wall of metal dividing the turbine/wastegate exhaust paths.

Do you mean to say it's not a curved wall?

I know David Buschur did alot of testing on this subject to prove
there is little to no difference between either the 2.5" and 3.0"
versions. Do a search on this topic.

We have dynotested the Megan O2 housing to be the leader in tubular O2 housings.

We have a special this week on them for $75.

Is there any chance this special was extended?

I'm also interested if it's still for $75. Does porting it add any significant gains?

You cannot port a tubular O2 housing. Its made of relatively thin walled steel.

And yes the contour of the wastegate exit makes a sizeable difference in velocity and flow of the exhaust gasses.

I have the Ebay/Megan Racing unit for sale. It is fine but I obviously went with the EPM unit. It is the very same David Buschur picked up 15WHP on with his race car.
