General consensus is keep the airbox. The white jug is a silencer so it's optional for N/A. Not sure for the LGT.

Now, given this is with a Stage II map - it still shows that the silencer DOES have an affect on the performance of the engine.

I'm throwing my silencer back in when I go Stage II today...
