Anyone removed this with the stock airbox still in place on the MS6? I want to remove mine hope I can hear the turbo or Factory BOV.

Performance gain? Performance Loss? Any inputs? I will get a CAI later when I have money.
 
Crap is it worth even doing at all? No gain?

I know when I get the CAI I have to do it anyway.
 
I didn't notice any difference performance or sound with the resonator delete. The only benefit I saw was that it made the CAI install alot easier.
 
I tried driving around with the airbox open. Sounds 500% better. You can hear the turbo spool and the recirc valve. Sounds almost like a BOV.
 
What does that thing even do anyway? I looked at it when I was taking it out and it doesn't seem to do anything.
