Ford Exhaust System :: 1996 F250 - Drone Noise At 1900 RPMs?


Feb 28, 2014

I have a 96 f250 7.3 I just cut the cat and muffler, and developed a drone @ 1900 rpms. if I shift out of OD it goes away if I get to that rpm in OD it drones. What would be my best plan of attack to get rid of the drone? Hollow out the cat and re install?

Ford Exhaust System :: 1996 F150 - Exhaust Making Strange Howling Noise

Ok, probably about 1/3 times i start my 96 f150 4.9 with true duals, the left pipe has a higher pitched howling noise, its a steady tone whether I rev the truck up or not it just gets louder. It will do it for about 6 seconds and then stop. The truck doesn't run badly because of it, but i took her to autozone to get her scanned and they said that the oxygen sensor on the first manifold bank has a slow response on startup. Is that what causes this strange noise, I don't even know how it would make it, it sounds much different from the engine. The right pipe doesn't do anything.

Ford Super Duty (1999-2016) :: 2012 F250 6.2L - Drone / Vibration When In Drive Between 1600 - 1800 RPMs

My 2012 F250 6.2L (Gas) engine developed a noticeable drone/vibration when in drive between 1600 - 1800rpm. RPMs above and below that range is fine. But when accelerating, as soon as the RPMs reach 1600, you can feel a slight vibration through the gas pedal and a noticeable sharp draon/moan up till about 1800 or 1900 rpm, then its normal.

I took it to my ford dealer and took the service manager out for a test drive. He said that there is a drone and slight vibration withing that RPM range. He thought that the engine mounts may be loose. But aside all that, he felt something was off and wrote up the service order.

When to pick up the truck and now the service manager changes his tune and said that the drone is normal and happens on all 6.2L super duties.

To be honest, I have the feeling he is pulling my chain.

Golf IV / Jetta IV :: Growling Noise At 1900 RPMs When Car Is Under Load

I recently purchased a 2003 jetta 1.8t 5 speed manual and it wasn't making this noise when I first bought it.. It's almost like a growling/grinding noise. It's sounds like it's coming from my middle console but it could be coming from the engine bay hard to tell, but the only time this noise happens is at 1900 rpms when the car is under load like if I'm going a hill it's pretty loud when I'm going slow, the previous owner had the water pump, timing belt, and clutch done 10k miles ago. I have a feeling it's from the clutch/transmission or maybe from the timing belt?

Ford Exhaust System :: 1994 F250 - Replacing Exhaust?

I have been thinking about toying with my exhaust. I don't have a crazy amount of money. I got a 94 F250 with the 5.8 liter 351. Heres what I was thinking. Get rid of everything after the cat, and then run a single 3 inch pipe from the cat to a flowmaster 40 series, and then exit either right before the back tire or right after it.

Ford 6.0L Power Stroke Diesel :: Missing When On Interstate Just Cruising Along With RPMs Below 1900

I get what I can only describe as a "missing" when Im on the interstate just cruising along with rpms below say around 1900. That seems to be when I have noticed it. It is not very frequent but often enough to not let me forget about it. Happens when I'm towing it seems more than when not. Seems the rpms have to be below 18-1900 and in 5th speed. You can just feel the truck ever so slightly missing like in the old days of points and distributor caps. No tunes

Ford Exhaust System :: 1987 Ranger - Engine Is Running Very Rough And Seems To Miss At Low RPMs

How many O2 sensors does a 2.3 fi 4 cyl. have. I think just one on the manifold, but I'm not completely sure. Engine is running very rough and seems to miss at low RPMs, has no power and drinks gas like crazy!!! Emissions light is on on the dash. I'm thinking O2 sensor......tried replacing, but couldn't get enough torque on the sensor socket wrench to loosen, may be rusted.

I plan on putting a catback exhaust on my 2016 F350 6.2 gas engine. I have always loved the sound of Flowmaster exhaust but over years have started to become slightly annoyed with the drone in the cab. Is there a exhaust system out there that is capable of sounding like Flowmaster but without the in cab drone.

Ford 6.7L Power Stroke Diesel :: 2014 F250 - Exhaust Fluid System Fault

2014 F250 Diesel... I got the msg saying 50 miles until speed limited to 50 mph. None of the earlier warnings re adding def. check def on computer and it said it was ok. I even added def and it only took a small amount until it overflowed. It was more than 1/2 full. The error message did not reset. I drove it around for several miles and it still would not reset. Having it services as we speak, and the tech is still having difficulty running down the cause. He has done a regen,and reset the computer and etc and still has not resolved the issue..

Ford 6.7L Power Stroke Diesel :: 2015 F250 - Exhaust Fluid System Fault

I bought my 2015 F250 last November, and this spring my check engine light comes on with the message exhaust system fluid fault with the anoyying speed limitation. Bring the truck back to the dealer and they just say add def fluid, so I just have them do it. 2 weeks later the message comes back, bring it back to the dealer and they tell me it "needs reprograming" they do the work, light goes off. two weeks later light comes on again. Dealer puts in new exhaust sensors and reprograms the truck.

This fix lasts a few months in the mean time the truck shutters really bad under regeneration mode. Talk to dealer they claim its normal. Finally this week the light comes back on again. Bring the truck to the dealer and Ford keeps telling them that it only needs reprograming but that doesn't fix the problem. The dealer wants to replace the computer but ford isn't letting them do it (the truck is still under warranty) . I am starting to get pretty mad when I went out and bout a 65k truck not to have these problems.

Mazda - Mazda3 :: High-pitched Gargling Sound When Accelerate And Tachometer Reads 1500 - 1900 RPMs

I'm having a problem with my 2012 Mazda3 (automatic, non-skyactive model) that others seem to be complaining about on the online forums, but there seems to be no consensus.

About 10,000 miles into owning the car, it started making a sort of high-pitched gargling sound when I accelerate and the tachometer reads 1500-1900 RPMs. At first, the sound occurred sporadically when I was accelerating under these conditions, but now, at 28,000 miles, it's happening almost every time I accelerate between 1500-1900 RPMs. Here are a few more facts:

The engine must be warm. The car must be in drive (I cannot replicate it in neutral or park)The sound occurs regardless of whether the AC is on

I took it to the dealer 3 times. The first time, they changed the belt, and that worked for about 1000 miles. The second time, they told me that the noise is normal, and I should not worry. The third time, I took it to a different dealer, and they put a "dressing" on the belt. That worked for about 600 miles. Now the sound is back again, and it's driving me nuts. It definitely doesn't sound normal. If I test drove a car at 28,000 that made this sound, I definitely wouldn't buy it.

Ford Exhaust System :: Slapping Noise At Full Throttle

Any turbulence in the exhaust note, ie. slapping noise at full throttle. I have run 3 different mufflers in one year on my true dual and also gutted the cats. I currently have 2 1/2inch true dual with gutted cats and cherry bomb extreme mufflers. I Also am running an H-pipe, but I feel it isn't doing its job so well to balance the two sides. My trucks exhaust is almost perfect, it starts mean and loud, and has limited drone at highway speeds and great flow and power, but when I am smashing down the throttle the exhaust goes everywhere and makes all sorts of weird noise.

I almost feel that I should of went 3 inch to allow for me air to get out of the motor, I think the 2.5inch is restrictive possibly hence the air is having a tough time squeezing out of the system. But anyway do you think if i ran an X pipe it would work? Its my last option because otherwise i may convert back to the a single 3 inch dual 2.5inch outlet again, i miss my old set ups mean consistent tone at full throttle.
