Hey i was thinking you could always add a component
set under the dash firing in to the floor or make a kick panel for the floor with a 5.25 or 6.5 be real easy and noone would see them and you wouldnt tear or devalue anything

Many people have put on dual mufflers with double outlets over the years. I don't remember what mufflers they used and I don't remember thinking that sounds great...I need to do it.

I have built exhaust systems over the years and in general on V8 and I like using an H or X cross over for mellow sound.
The mufflers them selves have been generic "Turbo" style and if a catalytic converter is required there is a high flow generic "Cat" available and I have used that when ever it is needed.
On I-6 engines duals just was not cost effective and I use a large pipe with a Glass Pack. It is a bit on the Raspy side but I have gotten used to it.
I guess what I am saying the weather is not hard on exhaust systems here and if I need one I generally go generic budget with out a brand specified. A four cylinder car is a problem. They generally sound a bit raspy. I don't really like that. My Saturn, a 94 is still using the OEM exhaust system.
But
On my Hornet which is going to be a V8 with a lot of cam and carburetor I am going to have the exhaust system built with the largest diameter pipes I can afford to have made for it. It will have an X or H cross over, preferably an X but I can live with an H. I am going to save my money to buy FLOWMASTER brand which in my opinion is a first class brand with a lot of choices.
I am going to try to pass smog with out a catalytic converter as the car was originally spec'ed out to pass smog that way. But I will leave room to install the generic high flow Cats and I already have a smog pump mounted, it just needs to be plumbed to the nipple on the Catalytic converters and I am sure I will be to tune for smog criteria if I need to.
Should the Saturn come up short, I will again use the generic High Flow cat and I think I will have a Flow Master muffler plumbed in. There are many options that way. Again, here is not hard on exhaust systems, so they last a long time
My oldest is on a 1980 AMC. I still am using the OEM head pipe. The catalytic converter has been replaced with a high flow generic cat and then the one I took off was re-installed on a 1980 AMC AMX that the catalytic converter had rusted out.
options can be seen here:
http://www.flowmastermufflers.com/
And in this part of the country ALL exhaust systems are custom built. The tubes are bent and plumbed as needed.
And they are good at it. The negative. The material is a mild steel. It works here due to lack of corrosion.
But try to do the same thing and drive it in a salt covered winter snow street, I doubt it would last the season much less the winter.

Things I've heard recorded and then replayed on the internet all sound pretty much the same to me.

its like john said all in a nutshell,cant get a v8 sound out of a 4 banger i know that,but i just dont want that yoshimira sound of a motorcycle,i wanted a european sound,and was hoping someone could back this thought of mine,but i cant find it so i'll be he first,but i said before my car was 100 ucks and needs some work firstbut im going to order all the parts i want when i get my taxes and do everything at once,and go pull a engine and start building it so when i blow this one up i can "JUST" swap hem out.

If you dont want the raspy sound i suggest a long resonator. I have the header with 2" piping to a glasspack and a super 40 muffler. The resonator im using right now is too small and the engine sounds real raspy after the rebuild. I got the longest resonator the store had (about 10" larger than the one on there now) and im putting it in soon hoping to drown out the rasp. Ill let you know how it works

An opinion on RASPY 4 cylinder engines.
Most of the reason other than a 4 cylinder engine being small and of fewer cylinders and of high rpm naturally sound raspy is not the engine but the location of the muffler.
As a V8 is 2 four cylinder engines, the only reason that they do not sound as Raspy is generally they are bigger AND you can tune the exhaust system with cross over pipes. But the engine is not the significant factor.
The location of the muffler is.
When they are located at the extreme back of the car so that there is nothing after the muffler except the out let. There are no pipe lengths to mellow out the sound to let them resonate with.
Even a V8 with dual exhaust sounds raspy with the mufflers located just forward of the rear bumper.
That makes the muffler itself very critical in the final sound of the engine.
For example. The Chevy's through the 60's and 70's have an almost absolutely beautiful engine sound. The should. The mufflers are located almost under the driver and passengers feet. The cars are wide and room for them was made in that location. That leaves 2/3 of the length of the car to allow exhaust pipe length to Resonate create a mellow deep sound. When you move the muffler to the rear bumper you have 6 inches of pipe and it BLATTS.
On my Javelin which initially had headers in duals. The headers after way too many years of dealing with problem prone leaks caused by them I replaced them with an efficient Cast Iron exhaust manifold and (this is the important part) a cross over H pipe to get rid of the Blatty Drone the exhaust sounded to me. The exhaust mellowed right out. The cross over made a big difference.
You cant do that with a small 4 cylinder engine and a single pipe.
Common Street Practice today seems to be remove the catalytic converter and put some kind of a muffler with an over-sized outlet directly forward of the rear bumper.
Yes I know the reasoning why. This is not my first Rodeo. The "back in the day" equivalent was a glass pack and an echo can. What was an echo can? Just what it says, it emphasizes the Blat caused by a glass pack on what was then a small in line 6 with a single exhaust or Straight 8 or even a V8 with a single exhaust.
Todays performance mufflers emulate an "Echo Can"

That also means to get rid of the blatty or raspy sound you have to have a better muffler design.
The Flowmaster Super 40 is a 2 chamber muffler designed to be used with a Big "V8". And while it is 1/2 of a V8 when in duals, half of a 5 Liter mustang is 2.5 Liters so it is still when used in general, on a small in line 4, the muffler is still large in comparison to what is needed.
And there is no H or X cross over that can mellow things out. A 40 is a 2 chamber muffler.
The 60 series Flow Master is a 3 chamber muffler and while it is a performance muffler it is also designed to be a quieter muffler and used on smaller engines.
Where as the 40 is a 2 chamber and based on race muffler technology.
A smaller engine can get a way with using more muffler because it does not NEED the size
I don't have much in dyno testing articles these days but what little I do have pretty much says that if a 60 series was used instead of a 40 series the muffler tone would be less raspy and there would be no measurable change in performance.

Which comes down to catalytic converters.
Pretty much all states require some form of smog testing. While there is areas with in a state that generally do not, most will. Which means a Catalytic converter is going to be required. As I live where that is required when I built a motor it will pass a smog test in my state.
How it passes is another story, but it will. And one of the requirements is a Catalytic Converter must be installed.
Again, lack of data prevails, but on at least one performance engine I have, a small I-6 engine I was using the original OEM GM designed Flat Catalytic converter. I needed a new cat for a restoration, it was on my small engine street racer so I removed it and installed it on the restoration. I then purchased and installed a generic (available easily in my area) Catalytic converter. A high flow model. It was affordable and available.
And drag strip performance numbers showed no change in performance of the car. The message there is simply. The OEM Catalytic converter, an early flat style not known for it's efficiency was still more than adequate to do it's job which was to pass smog.
A high flow cat made no difference.
I have since used that particular inexpensive high flow cat on other applications.
I am a firm believer in a high flow cat if I have to have them.
And they help mellow out an exhaust note.
So the objective would be to have a nice sounding exhaust system with out causing a negative performance problem.
From where I sit a generic or not high flow catalytic converter in conjunction with something equivalent to a Flowmaster 60 series muffler probably gets as close to meeting that as anything I could think of.
But face it, exhaust modifications are not cheap. Those two parts probably add up to about $250.00 in bits and pieces and add in the cost of installation which may run another $250.00 you are talking $500.00 or near abouts in exhaust pipes. Which frankly I don't think you are going to get much in the way of measurable performance out of.
AT least not on something that has a small engine in the first place AND the exhaust system is in good shape.
To me, $500.00 put into installing a good cam is a better buy and leave the stock exhaust system alone.
I make it a habit of leaving exhaust alone if there is no need to replace anything at all. Especially on small engine cars.
But if I ever have to deal with my Saturn that is the way I would go. A 60 series Flowmaster and a high flow aftermarket catalytic converter.
