I think someone should make a "full" dp for the lnf. One that goes rights from the turbo flange to the exhaust flange in all 3"

 

That would be a bitch to change out. Mine as well change the turbo while you're doing all that.

 

Considered it here, as we are and have been working on one... It would most likely require a "v band setup" to allow for installation. Who would be interested?

Having a large head unit, should increase for a quick spool up, BYT and us have been talking about it.

 

The factory o2 housing flows pretty good. It's quite large very durable. The only gain to replacing the o2 housing would be a little bit of weight reduction.
