Hi , I am new to the group. I recently got a 2000 F250 SD with the V10. I have been online on various pages searching about this issue . I am not exactly sure that is my issue but seems similar to other postings I have read. On one of the other forums in this group someone posted that they had put a video on here relating to the sound. I can't seem to find that, I think it was posted a couple of years ago.
Does anyone happen to have a sound clip of V10 exhaust flutter ? I only hear it for a few minutes going through the first 3 gear changes and then it clears up. I have a video I took inside the truck and what I am hearing just in case someone can verify that's it for exhaust flutter. Will try to figure out how to add my short video. Any help will be greatly appreciated.
Truck runs great and as I said I have only had it about 5 months.. Also,just my luck about 2 months in I popped a plug and had that repaired.

 

I don't have audio clip of it but the resonate flutter is in the Y pipe on the right side and it sounds like a mix of lifter noise and exhaust leak but it's only at certain rpms, it also gets loader under load. The other noise that is mistaken is a loose bell housing inspection plate or bad welds on the heat shields. To eliminate the inspection cover just take it off and see it goes away, inspect the heat shields.

I had two 2000 V10 F350 trucks both I had from new. My F350 CCLB SRW was a very early production and didn't have PI heads (power improved) and it had no flutter but my late production F350 SCLB DRW with PI heads had it from day one and after some calls to customer service and a 6 week wait for parts they fixed it with a new Y pipe and a new program for the computer, the old Y pipe was the rams horn style and the new one was the necked down style. The new Y pipe solved the problem and it had improved performance after the fix, I had that truck for 13 years and even after putting a Banks Cat Back Power Pack on it the noise never returned..

Be careful doing that... in my case, removing the bellhousing cover made a REALLY REALLY LOUD buzzing sound from the engine separator plate. It goes both ways

 

I took mine off and sandwiched a piece of rubber at the bottom edge. Completely dampened it.

 

Today 1/24 I spent working on the truck and my quest to find the source of my dreaded "exhaust Flutter" .
I looked at several areas that had been suggested. First I looked at the Torque converter shield, I started to lossen the 2 bolts and found that was not going to help because it appears that the plate is actually attached to the transmisson/motor bolts. Didn't appear that shield would just drop off by removing the two bolts as some suggested. So I couldn't pull it to see if removal would stop the flutter. I did however as some said they did, take a screw driver and pry out on the bottom of the shield to see if that did anything. It didn't change anything.
I ran a scan and found that I needed to replace a coil and plug on one cylinder, did that. Nothing changed.
Crawled under the truck again to look at the exhaust manifold studs. I did see 3 that the end of the stud had broken off along with the nut. Didn't appear to be any leaks or black soot around those studs though as to show a leak.,they were clean.
Looked over the Y pipe, mine did not appear to have the drop down in pipe size to the Cat. Cat appeared clean, no holes.
I don't know what to do, I guess live with the flutter that you hear around 2K rpm with each shift and them runs fine, even sounds good at idle. May have to try to find a shop that has dealt with this sound before.
I am at a loss.

I'm on my second F350/V10. Both had the flutter when cold, and it goes away after a few minutes. Both had the factory Y pipe removed, and the SPD Y pipe installed. Flutter was still there,
just slightly different. I've come to accept that its normal for the V10.
The flutter is not related to broken manifold studs.

 

The inspection plate will come off, it has to so you can get to the torque converter bolts. The top photo is the Y pipe that will eliminate the flutter and the bottom one is the rams horn that causes the flutter.

 

I tought so too. I am used to the Chrysler converter shields that just drop off with bolt removal.. This one you could not actually feel a seperation of the shield to the engine block and transmission itself,Kind of like the plate went up between the two.

 

I guarantee it will come off

That is a most interesting comparison. I'm a retired steamfitter / welder.... The top photo shows what we term a "dead head" which will cause cavitation in liquids. The bottom photo shows more of a "Y" intersection, directing the flow down stream... Which allows liquid to flow more easily....

Thanks for sharing.

On both of them I think they were trying to get equal length runs for both sides but the bottom one created a resonate sound at certain rpms with PI heads where the necked down one eliminated it , all I know is it worked and I wasn't going to change it.
