I searched High and Low here on YouTube and could not find a video on the best recommendation on removing the turbo silencer but also how to get out the turbo housing to do so. I hope this video helps you in the long run and will state I AM SO GLAD I DID THIS.

Removing the Silencer Ring has allow my turbo to whistle like crazy "which I Love" but has also allowed my diesel to work and sound like it supposed to be. The nice thing is for the diesels out there that are not deleted and you want to free up some airflow "AND" add let your turbo stand out then definitely get this done.

All in all took me about 3 hours to remove the necessary parts to get to the housing, drill out the 3 pins, and then put everything back together again. Only a few simple tools such as sockets and wrenches will get the job done.

NOTE removing the wheel well/rock gaurd will allow more light in the areas needed to work on plus will free up space to get the boost tube boot sleeve on vs. doing it up top on the engine side.

    You should have searched high and low on the numerous forums out there about this. You would have learned that this isn't a "silencer ring" and you shouldn't remove it. The "whistle" you now hear is from increased turbulence because the thing that helped air flow more efficiently into your turbo is now gone. If you want your 6.7 Cummins to sound like a "real diesel", you're going to have to remove the EGR/Cooler, manifold, VGT and throw on a 2nd gen style manifold, fixed vane turbo, and a straight pipe.

    I did this a 2 years ago. Now I’m replacing my turbo. Just a heads up
  • @ChaseLandMgmt
    Lol. Added turbulence into the intake. Got some sound, lost power and mileage.
  • @D.M.Designs
    All the people saying turbo is "ruined" does a vacuum cleaner care what shape is on end if it is the same opening size? That turbo is making boost regardless of that ring or not. That turbulence definitely ain't stopping it from making boost. Just like the waterfall ain't changing depending on the whirlpool on top of the dam being there or not.
  • @cfnibertcc
    The video doesn’t do it justice, I’ve put over 200k on my turbo since I “ruined” it in 2008
  • @diesel09
    Wow. Shoulda researched a little harder on this “mod” lol
  • @michaelmitchell5787
    The engineers that designed that turbo did not put that in there for sound reduction. I can assure you it improves the aerodynamic flow of air into the turbo. Oh well less power but it sounds good. You know what else helps airflow? Full delete!
  • @raymedorio1930
    That is not a silencer ring! Just put a intake cone air filter!!!! Remove that big ass air filter box and you will hear the difference!! I did it on my 09 cummins!!
  • @davesmith1425
    You should delete that ccv hose so that oil don’t back in your turbo.
  • @Jonathan-NC
    My 13 3500 longhorn with everything deleted and straight piped sounds louder then that one 😂😂😂. Don’t do what he did lol
  • @cooperdanieltherancher
    This is a bad mod. That ring helps air flow into your turbo easier. The whistle you are hearing is vortexes inside your turbo that is restricted air around the intake on the turbo. If you want a louder truck delete it, straight pipe it, and get a tune done on it. DO NOT RUIN YOUR TRUCK WITH THIS MOD!
  • @brettrichards666
    Still sounds like a grandma car. Just delete it and straight pipe it like a real American.
  • @Coaltrain87.
    Absolutely do not I repeat do not do this you will cut the life of your turbo in half if not more!
  • @joeblecha6573
    Yup don't do it you'll trip your CVV code and you can't fix it
