Ford Exhaust System :: 1996 F150 - Exhaust Making Strange Howling Noise
Mar 31, 2008
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.

I currently have dual exhausts on my 2002 F150 and that's all I have besides stock for the exhaust system. How can I make it louder without getting rid of the duals?

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?

I have a 2001 Chevy Prizm that I just had the front pipe replaced on. It was not accelerating well and making noise. New front pipe and it feels like a new car. The check engine light came on. i cleared the code, drove it for a day or so, and the light is back on. My exhaust mechanic says we don't really need to worry about the cat con hurting our engine unless we see a decrease in performance. Are there any mechanics out there who would say that is true. The car has 160,000 miles and we want to see it go another 100,000 or so, and not do anything to damage the engine.

I just got a brand new 2008 F150 supercrew FX2 last wed. I love it, it's my first truck ever and I'm excited to drive it. I wanted to change the exhaust to something that has a low rumble and is deep, not too loud or anything.

I have a 95 f150, Eddie Bauer, extended cab, 4x4, 302, 285 tires. My question is this... What happens if I remove the second cat. I am trying to get a better sound from the exhaust and have been told the second cat is making that impossible. There is no o2 sensor downstream of the second cat, so I'm thinking the computer will never know its gone. Also how well this affect power. With the bigger tires, it's kinda sluggish off the line.

The truck in question is a 93 F-150 X/cab 4x4, has 5.0 5spd. So yesterday i replaced my exhaust with pre made magnaflow "y" pipe/cat with a flow master 44 then new pipe all the way out. When i start the truck up this morning to let it warm up a little it started to give off a funny smell almost like brakes/electric burning smell. I was wondering if this is common for new pipes to burn off any oils that may have collected on them from the factory. I look under the truck and nothing is touching the exhaust, but the shiny new pipe is starting to change colors. So do you think it will go away in a short time? I have to an appointment about 30 miles away on the freeway think this will burn off?. BTW there was no smell prior to the exhaust change.

Had the check engine light in the 2005 F150 (90,000 miles) come on. Got the code checked and its P0420. I know that has to do with the cat threshold levels etc. So I believe I am looking to replace the o2 sensor, if I am not mistaken.
How hard of a job is this? Ive done a decent amount of engine work. Just looking to see if that is the right thing to try first, replacing the sensor, before replacing the cat.
Also I know its the right bank, but if I am not mistaken there is a before and after the cat o2 sensor, which do i replace? Both?

So I was wondering where the O2 sensors are on the 04 f150s and if I could cut the rear set of cats out without throwing off those sensors?

I tore it apart and there was no gasket or donut ring in the flange. Is there supposed to be a gasket or donut ring? I can feel the leak with my hand. I have retightened & it still "tick-ticks" real bad.

I have a 90 bronco with a efi 351w and im missing one nut for the manifold to exhaust pipe flange. I have looked all over the net and can't find the size I know its a 1/2in socket but I need the thread pitch and size, had the parts guy try to sell me the stud and nut kit seem really expensive for just a nut and to install the full kit I have to pull skid plates and the trany supports just to start to get room to do the job, seems like a lot of work to replace 1 nut...

I just purchased a 2003 V10 with 270 000kms. The truck had had regular maintenance. It has an exhaust leak and runs a little bit rough. Could the exhaust leak cause the truck to run a little rough or am I dealing with another issue?

My F150 exhaust seems rather quiet when I first start it up, but after it gets warmed up good, the exhaust is much louder (which I like). I started wondering if I had a crack up front that widened out when it got hot, so looked under it when I got home today with it hot and still idling, but didn't see any cracks. Also I did not hear any noise like a leak. All sound was coming from the side exit pipe. So... what is the phenomenon that would cause this?

Leaking exhaust manifold? The truck has a much louder than normal "knock" when accelerating. At first I thought and had some bad fuel in the tank. I eliminated that with a full take of good fuel and some STP but the "knocking" continued. Then I thought that perhaps it wasn't firing on all cylinders but it felt like it had full power. I took it to my mechanic and he said it as a exhaust manifold leak. He said that he has never replaced the exhaust manifold but that it was a "nightmare" and expensive. He also said that it's not a safety issue but on the long run the leak would cause the truck not to pass its emission test. He said the problem was with rusted bolts that would be difficult to remove.

I have a 94 ranger 4L. I am looking for a more loud exhaust sound in/outside the truck and at idle. I have had a cherry bomb turbo on it and it was ok but not loud enough for my liking. I just picked up a flowmaster 40 2 days ago and it sounds good but again just not loud enough for my taste and kinda a lot more. I was looking for a louder muffler that is not a glasspack and would like to stay under like 80 or so.
I also thought about getting a high flow cat which i think might make some more sound but was not sure. Im running the stock pipe which is 2" and end in back of the wheel on the right. I look at the Hooker Headers Maximum Flow Muffler which i thought would be louder b/c it's more straight through the muffler so it would put off more sound better. What would u recommend for something more loud ?

My truck just started running really loud when it's cold and the leak goes away when it warms up to operating temperature.I did a little bit of investigating and I have found where the leak is coming from at the end of the exhaust manifold where the donut gasket meets the catalytic converters. It appears that the bolts rotted that hold the system together at the gasket. What should I do to repair this? I don't really want to replace the whole manifold because I know I'll break a stud off in the engine because everything is pretty rusty down there. I even took some pictures of the problem....

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.

i have my 4 inch exhaust pipe cut just behind the rear of the cab right now with no muffler. If i cut it further up maybe jsut under the front seat or so what would this to the sound? would it make it deeper or louder?

Why it won't work. copper exhaust coming off the headers. I have the ability to get it and bend it and how cool would that be copper duals. Why won't it work. If I bolt it right to the headers.
