The bungs are there for anti-lag systems... If you do not run anti-lag which no cars in the US do unless its aftermarket, you just plug the bungs up with a bolt that threads into them... Thinking about it, you may even be able to get an egt probe into one of those bungs... I dk if it'd be the optimal place for one, but it may work...

From what I know FP outsources for these manifolds and they look exactly like the Tomei manifold. Dont quote me on this, but im sure they outsource. Good looking nonetheless.

The 2 bung are also called "secondary air intake". In WRC they utilize them as
Anti-Lag system or Missfiring system, it's standard on all Japanese EVO,
not on US EVO. You have to plug them if you are using in USDM EVO
this is a quality piece, the design is almost identical to HKS manifold for fraction of the cost.
Also this is also identical to GT SPEC manifold as well.

its going to be very diffcult to find someone with accurate data on just a manifold swap from stock.. I made 430whp on a megan w/ IX turbo and i would attribute alot of it to the tubular manifold and i think I would make as much or more than a megan..
