How do you get to the silencer ring?

This might help ya - Silencer Ring

pull the air filter elbow off of the turbo and remove the snap ring and it pulls right out. I used 2 screwdrivers to get the snap ring out, just make sure not to gouge up the housing it is aluminum and will peel off and if not careful will go through the turbo.

i did it doesnt do any performance but sure sounds good.

Maybe I'm going deaf, couldn't hear a diff.
