Ford Exhaust System :: Exhaust Quieter When Cold / Much Louder When Warmed Up

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?

Ford Exhaust System :: Exhaust Manifold Leaking / Louder Than Normal Knock When Accelerating

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.

Prius (2004-09) :: Exhaust Noise Has Been Getting Louder

So recently (since Thursday morning last week) I noticed the exhaust noise of my prius has been louder. Today I experimented a bit and I'm pretty sure it's exhaust related. The car is pretty loud if there is any load on the engine, although still mostly quiet if it's idling. There are no errors presenting and mileage is still great.

Otherwise, it's loud and resonates at a few different rpm points, and I found that when the engine spins under breaking (foot-off coasting over 42mph or in B mode) it also makes noticeable exhaust noise of the same type.

I'm guessing the exhaust is leaking (the sound seems to be coming almost from the left rear seat area? Behind me when I'm driving at least).

Golf IV R32 :: Exhaust Is Louder After Flash Upgrade

I recently flashed my car and not to happy about it. For me the car feels a little different than stock. My exhaust is louder and when I start the car now is doesn't start from high revs down to low anymore. I think I'm going to take it back and remove the software from the car. I personally don't like the feel as to stock.

Golf IV / Jetta IV :: How To Modify Exhaust To Be Louder

So I acquired a 2003 1.8t GTi a little bit ago and i'm loving it, but I want it to be louder and more aggressive. With that being said I've already searched the forums but could not find anything for my specific case. I bought the car with a 3 inch downpipe and Borla muffler installed so I would like to know what way I can modify the exhaust to be louder while keeping these components in tact!

Elantra XD (2001-06) :: Exhaust Leak Between Front Cat And Connecting Pipe

I changed my front catalytic converter yesterday. Everything was installed properly and the repair went smooth. Unfortunately when I started the car, I discovered the connection between the bottom of the cat and the connecting pipe was leaking out a ton of exhaust. The previous cat didn't leak like that. I put in a new gasket and tightened the bolts extra tight but the leak is still there. The worst part is that the leaking exhaust fumes are all traveling up into the hood, which makes it look like the engine is smoking. What should I do to stop the leak? I even tried using muffler tape but that only worked for an hour until it hardened and sounded like crap.

Elantra XD (2001-06) :: 2004 - Leaking Metal Coolant Pipe Behind Exhaust

As shown in the photo, the metal pipe that runs behind the exhaust manifold is leaking coolant. I can't see the leak (obviously), but I can feel it with my hand (after getting burned on the exhaust!) It is NOT leaking from the right hand clamp of the metal pipe. How do I remove this pipe to inspect? Do I have to remove the exhaust to get to it, or simply remove the right side clamp and some bolts?

Elantra XD (2001-06) :: Exhaust Leak Sound From Engine Compartment Only At Cold Startup

I hear a bit of exhaust leak noise from engine compartment only at a cold startup, it goes away in seconds. I am 700miles from home. If it's a nonessential fix i will drive home before fixing, or, if an easy gasket replacement, I have two more days here, and tools,garage, and competent support to diy the job.

Prius (Gen 2) :: Exhaust Louder - Water Drip Out From Engine Side Of Resonator

Noticed a louder sound to my exhaust. Cuts out when ice shuts off. Haven't got a good look at the whole exhaust system from underneath but did see water drip out from the engine side of the resonator when the car was warming up. The sound is coming from about midpoint between the taiI pipe and the engine. I suspect the weld at the resonator junction is breaking. Is this common? 2008, Canada, 130000 km.

Ford F-150 (2009-2014) :: Wind Noise Is Literally Louder Than Exhaust At 55 Mph

Ok, as promised I made a clip of my 2011 Ecoboost towing my 5-6K trailer with a 3" cat back MBRP exhaust. I gained over 2 mpg with this exhaust (MBRP) and intake (aFe) while towing. So far while not towing it only seems to have given roughly a 1 mpg increase over stock. I can barely hear the exhaust at highway speeds after the truck shifts into 5th and 6th gear. The wind noise is literally louder than the exhaust at 55 mph!

Gmc - Envoy :: Louder Exhaust Noise Than Normal When Start The Truck In Cold Weather

I have a 2003 GMC Envoy with 76000 miles on it. I heard a louder exhaust noise than normal when I start the truck in cold weather. I had it checked and was told that the exhaust system was OK but that the noise was because the motor mounts needed replacing. I have never heard of this before. Before I spend this money I wanted to see what your reply was to this question. Is it common for motor mounts to have to be replaced on this type vehicle with this mileage and age?

Elantra MD (2010-15) :: 2014 - Ticking Noise While Accelerating / Louder At Higher RPMs

I bought a new 2014 Elantra last Monday. Around 100 miles (Wednesday) I noticed it was making a ticking noise when accelerating. The sound gets louder at higher RPMs and goes away when I get off of the accelerator. You can't hear it over the radio but it's embarrassing when my passengers do. It almost sounds like a puff of air escaping or something, similar to a go-kart engine lol.

Anyways, I took it to the dealer Thursday and they drove it and said the noise was normal during the engines break-in period and if it persists after 15k to bring it back and they would see if there was something that needed tightening.

Santa FE SM (2001-06) :: Severe Vibration / Vents Rattle Louder Than Max Radio Volume

My wife's 04 AWD 2.7 Santa Fe has developed a severe vibration. I have rotated tires, checked ball joints and tie rod ends, and had it aligned. The tires show very even wear and don't appear to have any bulges or broken belts. The vibration is so severe that the vents rattle louder than max radio volume, but it completely disappears in even the gentlest right turn.

Subaru - Forester :: 2001 - Making Whining Noise / Louder And Slightly Higher-pitched As Accelerate

My car is making a sort of whining noise; it sounds like some sort of tire noise, but I checked the tires and don't see anything that could be problematic. My husband checked to see if anything was rubbing, and doesn't find anything. The car is quiet when it is not moving, and the noise gets somewhat louder and slightly higher-pitched as I accelerate. It almost seems like the noise changed on a different road surface, but again, I don't see anything different with the tires. The car has about 140-150,000 on it. The noise has only been noticeable for a couple of weeks. No other problems, no change in steering or handling. No incident that I can think of that could have been a catalyst.

Elantra MD (2010-15) :: Ticking Noise From The Exhaust

Since I brought my car to the Mississauga Hyundai dealership for an oil change and check up for a rattling sound my car has come back to this new ticking noise from the exhaust.

I had the dealership do an oil change (my own synthetic bought Quakerstate oil) and apparently they put a clamp/bracket because my exhaust was making the rattling sound. The rattling sound is gone, BUT i have this ticking sound every time after the car is shutoff no matter short or long drive. Also can hear it while driving sometimes.

I have took the car back to the dealership and they told me this is normal, the thing is my car has never made this sound before i took it to the dealership. The hyundai dealership claims that this is just exhaust cooling down/ heat expansion. I am curious to why it never made this sound before.

It is a 2011 Elantra gl with 67,000km here is a video after a 15 min drive : [URL] .....

Elantra MD (2010-15) :: Intermittent Strong Exhaust Smell

I'm going to take my Elantra in to get it checked. My Elantra is a 2013, got it in March. Over the last few weeks, I would say, on 4 days or so there has been a STRONG exhaust smell. No smoke, nothing else but a smell. If I'm pulling into the garage with no idling, just pull in and park, I get out and the smell in the garage is very strong. I have to leave the garage open for at least an hour if not more to air it out. The cab ends up having a light smell inside the next day still.

If I'm parking outside when I get out I can still smell it, but not quite as strong, because I'm not in an enclosed area. I don't think it's an exhaust manifold leak, because I don't hear the popping. My best guess is it would be in the tail pipe area pre-catalytic converter, or in the catalytic converter if it is in fact an exhaust leak.
