However, the removal of the silencer ring is a pretty common phenomenon with truck enthusiasts all over the world. Because removing the silencer ring gives the diesel engines a characteristic sound that diesel truck enthusiasts love!

But, the turbo silencer ring shouldn’t have any effect on the performance by design. The only function it serves is to quiet down a turbo a little bit.
Anyway, if you’re still on the fence about this, you should know removing or reinstalling takes only about 10 to 15 minutes, and you can do it yourself very easily! So, what’s wrong with trying once?

How To Identify If Your Turbo Silencer Ring Needs To Be Replaced?
Except in cases where there has been damage to the turbo itself or the ring has been damaged, replacing the turbo silencer ring is not always necessary.
The only purpose of the silencer ring is to bring down the whistling sound of the turbo a little bit. However, if you suddenly see a noticeable power loss with your truck or the acceleration seems off, you may check the turbo inlet.
Unless the silencer ring is obstructing the performance of the turbo in some way or causing damage inside the air inlet of the turbo, there are no ways to identify if the silencer ring needs to be replaced.
If you see physical damage to the silencer ring, you can find OEM silencer rings on eBay. Most companies do not sell silencer rings, and many owners remove them for fun! So, maybe ask around turbo forums for spare rings if you need one!
6.7L powerstroke turbo silencer ring removal step-by-step guide:
If you have a diesel truck and your turbo still has a silencer ring on, you should be prepared! Because diesel-hungry enthusiasts all over the world would just love to educate you on the beautiful music of the turbo!
Although the removal of the turbo silencer is quite a simple task, you can easily damage the inlet of the turbo if you don’t know what you’re doing. That’s why we wrote a step-by-step guide for you to follow.
Follow these simple steps to remove the silencer ring.
Step 1: Identifying The Turbo Air Inlet
The turbo air inlet is just the tube where air flows into the turbo. The inlet is connected to your vehicle’s air intake and supplies the turbo with air.
So, make sure you know where the turbo is. The turbocharger air inlet is a hose or pipe that is connected to the turbo and the intake of your vehicle.
Once you find the turbo air inlet pipe, you can move forward to step 2.
Step 2: Removing The Air Inlet Pipe
The silencer ring is inside the air inlet pipe and into the turbocharger’s mouth. So, you need to remove the air inlet pipe first to get access to the turbo.
However, this can be achieved very simply. The air inlet is usually attached to the air intake of the car with two or more hose clamps and two or more hose clamps on the turbocharger.
So, now you need to loosen up the hose clamps on both ends of the air inlet pipe, connecting both the air intake and the turbocharger. After loosening up the hose clamps, you can just pull out the turbo inlet pipe.
Step 3: Removing The Retaining Ring
After step 2, look inside the mouth of the turbocharger. The turbocharger’s mouth should have a dark gray colored, ring-like retaining ring. Some mechanics also may call this a snap ring.
This retaining ring is placed there to stop the silencer ring from bouncing around and making noise. So, the ring is clipped inside the mouth of the turbo pretty strongly.
However, removal of the snap ring is pretty easy as well. You can either use a needle nose plier or a flathead screwdriver.
The retaining ring is designed with a gap. The gaps are called free ends, and it’s designed to allow for compression or expansion of the ring.
Now, put the plier’s jaws or the screw-drivers head into the gap and push the ring outward. This may take some understanding, so tread lightly.
If you can just push the ring slightly out of the turbocharger’s mouth, you can simply grab the ring and pull it out gently.
This is probably the hardest part of this process, as the turbo can be placed at hard-to-reach places in the car. So, try to be gentle and careful not to damage the turbocharger.
Step 4: Removing The Silencer Ring
After removing the retaining ring, you can just pull out the silencer ring from the turbocharger’s mouth. The silencer ring is not attached to anything else.
The silencer ring is made of metal and is usually silver in color. You can just put your hand inside the turbo’s mouth and grab the ring out.
Step 5: Cleaning And Reinstalling Air Intake
The removal of the silencer ring is done at this point. Now you have to clean the turbo inlet for any debris or metal scraps and reinstall the air intake.
So, firstly clean the turbo inlet. Then, you have to put the turbocharger air intake pipe back in its place and tighten up the hose clamps as they were before.
Make sure that the clamps of the hose are tightened properly, the intake pipe is sitting properly, and you’re done with your job!
Enjoy!

Tips For Keeping Your Engine Running Smoothly With Your Turbo Silencer Ring Removed
Some 6.7 Powerstroke owners think that the silencer ring has some effect on the performance of the vehicle. According to them, removing the silencer ring will change the airflow into the turbocharger.
As the silencer ring is a large cone ring, it directs the air into the center portion of the turbo. However, most owners and mechanics think that the silencer ring doesn’t affect the performance in any way.
Usually, aftermarket cold air intake systems for turbos replace all the pipings of the turbo, keeping the turbo wide open, which increases performance.
So, having an open turbo will not disrupt the performance of your vehicle, and your engine will be running smoothly. All you have to do is proper maintenance of your vehicle and your 6.7 L Powerstroke engine.
However, if you’re still not sure about the merits or demerits of removing the silencer ring, you can keep the silencer ring stored somewhere once you remove it. Then, if you don’t like your truck without a silencer ring, you can put it back easily.
Conclusion
The 6.7 Powerstroke is a very strong and reliable Ford engine. The OEM turbochargers in these engines already sound pretty good. However, even novices can easily remove the silencer ring for a better turbo sound.
In this article, we discussed the simple and easy steps that you can follow to quickly remove the silencer ring from your 6.7 Powerstroke engine’s turbocharger.
However, we recommend you store the silencer ring and just try this mod out for some time. Also, work very gently around the turbo and air inlet to ensure you don’t damage the turbocharger.
