Quite as Possible.

I want to add a CAI but i live and work on an extremely dusty dry ranch so I need as much filtration as possible. Any recommendations?

I've read that the CAI will increase turbo noise. I'm deleting my DPF soon and trying to figure out how to keep this thing as close to the stock sound as possible. I pull a lot and don't want to listen to the exhaust or turbo all day long.

Any thoughts on this?

If you want to cut turbo whistle, add a packed style muffler like a dynomax ultra flo
