Hey, I'm new to the site and really like it. I have a 2005 LLY duramax and I was wondering what the purpose of the black box or "silencer" (as I have also heard it called) with 6.6L duramax written on it for. Will it make the turbo louder or not. I have seen a air intake company, Airaid I think, that includes a cap to replace the "silencer". Does it help? Any help would be great.
