Yes, at least half of the exhaust is coming straight out of that gap without passing through the muffler. As you've noted, this leads to an increase in noise (or music, depending on your taste).
To my eye, that looks like a hassle to fix on your own. There appears to be the rusted remnants of two bolts holding the Y-pipe to the passenger side muffler and ...

When the steering wheel is at the end of its travel (completely left/right) it is normal that the power steering pump starts making some extra noise
At max travel, the steering pump will produce its maximum pressure and will have to work the hardest. This will create a "hissing" type noise.
When the fluid level is low, then you will hear the pump moaning ...

You most likely have air in the system, I had the same issue with my 99 Blazer. It seemed as no matter how much I bled it it I couldn't get rid of it.
Raise the front of the vehicle make sure that the right side is a bit higher than the left. This will ensure that the highest point in the system is the radiator cap.
Remove the radiator cap and start the ...

That does sound very likely - it could be bearings, or as the volume increases when the wheel is turned it may be the universal joint.
Get your car propped up securely and spin the front wheels by hand. You may be able to hear or even feel whereabouts the problem is.
In any case, your local garage will be able to diagnose this very quickly and easily.

One cause of pops is unburnt fuel hitting the exhaust manifold - many engines use fuel to cool the cylinder when you lift off, so this sprayed excess then burns as it hits hot metal in the exhaust.
The burble on overrun is usually caused by ignition timing being retarded.
Aside from those, any valve or gasket leaks could also cause pops.

It could be incorrectly torqued wheels, loose disc brake calipers, brake pad shims, suspension pieces loading/unloading from the weight shift. If they just did the tires, take it back and tell them to take a look (for free).
Try slowing the car down with the engine. If it's manual, just downshift. If it is automatic, shift the selector to one of the lower ...

I happen to have the same experience as you when sitting in my 1998 Honda Accord after it has been shut off. The humming sound lasts 5-6 seconds, and it can be 5 to 10 minutes apart. The noise is definitely coming from underneath the car ahead of the rear wheels, not from the engine. I have also noticed that I have never heard the noise in the winter, ...

I am a GM mechanic with 25 years experience working on GM vehicles . I recently road tested a 2011 Chevrolet Cruze with a clicking noise from the right rear while braking . After having the rear drums off a couple of times, I found that the Gray grease installed at the factory on the rear backing plates had been missed in a couple of spots. The grease was a ...

Have you checked the Power steering pump/fluid level? I own a 2003 stream and heard a slightly heavier whining noise similarly tied to engine speed. You could try turning the steering end to end while engine is idling and listen. In my case it turned out to be a defective power steering hose.

I would suspect axle bearings more than U joints. Drive shaft noises usually don't change when moving left or right. You can check the axle seals for leaks. If the bearing is bad many times it moves enough to wear the seal. You can also check the axle housing for a temperature difference after a highway speed ride. It doesnot have to be an actual measurement ...

I don't think it's likely to be the source of your noise, but in the frequently helpful spirit of "check the last thing you touched," you may want to look at your power steering fluid level. Low fluid can make for noisy PS systems, and if you just had the system open, it's worth checking. Maybe the system was incompletely bled when you topped up the PS ...

If it is more of a squeel than a whistle you may have spilled antifreeze on to the serpentine belt. The anti freeze is making the belt slip. Is the smoke coming out of the exhaust pipe or off the pipes in the engine bay? If anti freeze was spilled onto the manifold and pipes it will smoke until it burns off.

After some deeper research, I have found that the cause is a worn thowout bearing. I also see that if this is to get replaced, it is wise to spend a few more $$ and replace the clutch as well as the labor to get at the bearing is the same as clutch replacment. So I guess I will be replacing both.

It is most likely a leaking EVAP hose or a leak in the fuel line. Make sure it's nothing obvious like a hose hanging off or a gas cap missing. Also check for a check engine light and have the OBD code read if there is one.
There is also a small chance that your fuel pump relay or fuel pump is the cause.

If it's a manual transmission, possibly the starter motor is slow to disengage and is grinding against the flywheel as the engine is firing up. The low oil is very suspicious though and doesn't go along with that. Could just be a coincidence. Or, could be pointing to something far worse. However, engine related startup scary noises are normally more of a ...

Sounds like you've got a little bit of air in your cooling system from when you replaced the radiator. It's not a huge problem, what you're hearing is just bubbles/air/water running through the heater core.
The method for getting air out of your cooling system is to place your Blazer on level ground or with the front just slightly elevated and run the ...

Turns out, it was the alternator that was getting weak or eventually dying. I took my car to the shop because my battery light came on whenever I started one morning and eventually had to tow it to the shop because my car died. The alternator broke and the bearings in the water pump were shot and needed replacing, according to the shop. Now with a new ...

A squeak like that is almost certainly a slipping belt. The easiest fix would be to pick up some "belt conditioner" spray from an auto parts store and spray it on the inside of all your belts, and see if the problem goes away. If not you can try tightening the belt that's causing the squeak; this is not too difficult, and just involves loosening a couple ...

I would imagine that if it was binding of the strut and it's seat causing the noise then the you would notice a few things in other characteristics of the ride. I say this
What kind of car is this? (year / make / model / engine)
How did you determine that the noise was coming in fact from the strut assemblies?
Was the rest of the front suspension checked ...

On some cars the fan for the heat, defrost, a/c does not have an "off" setting. The fan runs on low speed whenever the car is on. It is possible that the ignition switch is worn allowing the key to be removed with a set of contacts still partially engaged. If you turn the key to the "on" position turn the blower motor on high. Find a spot under the dash ...

I think it's the speedometer or speedometer cable. It happened repeatedly this morning (it seems like cold weather really brings it out). It really sounds like it's coming from the dashboard, and is correlated with wheel speed, and it sounds like the noise at http://youtu.be/ICiJuEBbf6A, except it's more consistent once it starts, and I don't laugh like ...

You should be able to tell whether the noise you are hearing is rattling, or vibration. They could have very different causes.
If you hear rattling somewhere in the dash, then it's probably something in the glovebox or various compartments inside. The first thing I'd do is to take away everything from these and drive around the block for a quick test. ...

If the shocks are an aftermarket brand they may have urethane mounting bushings. Urethane generally offer longer life and better performance. The draw back is that they can some times squeek. During installation a dab of grease will abate this for awhile. You can try to add a little WD-40 to see if it helps. If this resolves the issue remove the affected ...

My experience (in multiple cars, albeit not your make/model) has been that this sound always means your cooling system is under-filled. If you've emptied your cooling system and refilled it, it can be really hard to get all the air pockets out of the heater core, especially since in many vehicles it's almost as high as the radiator cap and at the opposite ...

Sounds like either you've got a warped brake disk or some kind of crud (possibly brake pad) stuck to the disk. Is it the same wheel your hand brake is connected to? Just wondering if you possibly got your brakes hot then parked and applied your hand brake. If so, that could have deposited a wad of brake pad on the disk. It should be easy enough to check, ...
