Exhaust Compilation By Model
Since I'm bored I figured I would take the time and list all of the exhaust I can find for each model of cobalt. If I am missing any feel free to let me know and I can add them. Below the article you will find the videos.
very wise/useful info here(especially since its from an integra forum...since we know how bad and raspy small displacement 4cyl sound...i.e. some exhausts on honda engines)

Exhaust design effects on noise
Posted 06-03-2002 at 12:00 AM by SurferX
Which exhaust sounds best? The question pops up all the time but no one can ever agree. Of course everyone has a different perspective of what sounds best on their car. I see it all the time, guys rolling around with their raspy weed eaters yelling praises to themselves about how awesome their car sounds. It's a fact, our low displacement 4-cylinder engines by nature do not emit a very respectable exhaust note. Try running open header on your car and you'll see what I mean. In order to change that high pitched rasp into a respectable growl we need a properly designed exhaust system. Different methods of reducing noise in an exhaust system Restriction- The easiest way to reduce noise is to simply restrict the sound waves from exiting the exhaust system. You find this used mainly in OEM mufflers where sound waves are directed into dead end chambers. This of course is the worst performing of the bunch, as the exhaust gas pulses will also be directed into those dead end chambers. Absorption- Most common in aftermarket muffler designs. The absorption method uses a perforated tube wrapped in some sort of insulating material. The quality of the insulating material will determine the exhaust note in these cases. An insulating material to stay away from in this case would be fiberglass, also known as glasspacks when used in mufflers. Fiberglass does not have a high resistance to heat and can melt over time making your car sound worse and worse. Reflection- This method decreases noise by reflecting sound waves into each other. This causes a scientific effect known as "destructive interference". If a sound wave runs into another sound wave of the same frequency and opposite phase, then the sound waves are both cancelled out. Thanks to physics master cheezthis for explaining that to me. Next page we'll get into specific exhaust parts and how they can be designed to achieve different exhaust tones. Let's look at the Integra exhaust as a whole shall we? An exhaust is just a pipe, no taboo about it. There are only two main pieces responsible for manipulating exhaust noise. When choosing an exhaust, you can look at the design characteristics of both of these parts and get a basic idea of how the exhaust will sound. Resonator These are usually installed a couple inches after the cat outlet. The resonator uses the reflection method and will determine the exhaust note based on it's size. The shell of the resonator is sized so th when sound waves enter, they will bouce straight back to the center and be cancelled out by the following sound waves. The longer the resonator, the more sound waves get bounced around and cancelled out. Some exhaust manufacturers will use two smaller resonators instead of one large one. The method that the resonator uses to decrease noise does not have any adverse effect on performance. Alot of people are mislead into thinking removing the resonator can free up exhaust flow. HyTech Exhaust in Irvine, CA tested their catback with and without a resonator and the dyno showed a difference of 2whp in favor of the resonator. In case you were wondering, HyTech used a Magnaflow resonator on their system which looks like this. Looks real restrictive doesn't it? ;-) Muffler Exhaust manufacturers can use a single method or combination of methods to manipulate exhaust noise with mufflers. The main muffler designs are chambered, straight-through, and twin-pass. Chambered This is mainly a combination of restriction and reflection methods. The dead end chambers like I mention earlier serve to keep sound waves from exiting the system. For sound waves that reach the end of the muffler, the majority are reflected back to destroy any sound waves that may be trying to get through. Very quiet but also somewhat restrictive. Straight-through Absorption is the name of the game here. The size of the muffler is going to play the most important role in how the exhaust note will sound. A short thin muffler casing will ensure a louder higher pitched note while a long and fat muffler casing will give a deeper and quieter note. Also, exhausts like the Greddy EVO are designed so that the pipe enlarges when entering the muffler. This slows the pulses down and allows more sound to be absorbed. That's how a muffler that is relatively sma like the EVO sounds much better than other mufflers it's size. So sometimes you also want to find out what the piping size INSIDE the muffler is, as that can also attribute to how the exhaust will sound. N1 Straight-through A more extreme design of the straight-through systems are the "N1" style mufflers. As you can see, there's little to no sound absorption going on here. Muffler is short and very small. Insulation material is kept at a minimum. This flows no better than a regular large muffler straight through however will sound much louder and high pitched. Couple this type of muffler with no resonator and you'll turn your Honda automobile into a Honda weed trimmer. "Hey my weed trimmer sounds tiiite yo!" Twin-pass The method used with this muffler to reduce noise is mainly absorption. The pulses have to travel through the muffler twice, which basically makes the muffler twice as long with twice the sound killing power. Also some acoustical tuning goes into making a muffler like this as well. With brass wind instruments, you change the note by selecting different length tubes for the air to travel. Longer tubes will give a deeper note while shorter tubes give a higher note. This type of muffler basic lengthens the tube, allowing sound waves to spread out and emit a deeper tone once exiting the system. The twin-pass design flows as well as a straight-through but will sound much quieter.

Exhaust Noise level Flow capacity Chambered (OEM) 1 1 Chambered (aftermarket) 1 2 Straight-through (larger muffler) 2 3 Straight-through (N1) 3 3 Twin-pass 1 3
It's usually a compromise of some sort, but there are ways around it. If you are willing to shell out the big bucks for a twin-loop system you will get the best of both worlds. Some like it loud, some like it quiet, it's up to you. There is no such thing as loud and deep with our cars, you get one or the other despite what the show boys tell me with their "super loud AND deep throaty" N1 exhausts. Some people have weird perspectives on what sounds "deep" so best to educate yourself on what makes a deep sounding exhaust rather than listen to whackos tell you how their weed-eater sounds "mean".

Awesome post man, exhaust is my next thing to do on my balt, after I get my Ksports installed anyways. This helps me try to make a decision considering I don't want my auto car too loud, lol.

I think this needs to be stickied. On another note I was searching earlier for these exhaust videos and my fiance is going crazy from the sounds of cars revving, lol
