i would be interested in the SPL (sound pressure level) of the mufflers also. And i want a better performance muffler but i DONT want the sound . I want the car as quiet as it is now. maybe a little louder is ok but only by a very small margin. I hate those cars that sound like blenders on crack.

if you want performance out of an exhaust system, a muffler alone will not do much for you. it can look nicer. but an advantage, in your case, of not replacing the y-pipe, which dramatically increases db level (as well as being the main element in any power gains from an exhaust mod), a performance muffler will be quieter anyway. in other words, your concern is not so much the muffler's noise as it would be the y-pipe. and it seems you want to keep the stock one. mind you, i have not gone this route personally, so i can only offer philosophy. but it seems to make some sense.
avoid, too, the huge bore "coffee can" type of muffler. i can tell you from my own experience with the magnaflow, that one produces a deep throaty sound and not the ricey buzzing annoying sound. i have heard a valet guy start up may car from afar and it sounds amazing, like a muscle car. and in tunnels or under bridges the sound is just awesome. like music.

Or check out the Greddy if you have the money to spend on exhaust. It sounds real nice.

my setup is basically stock except for my magnaflow. the sound is nice and deep, but drones crusing speeds. but it starts to get quiet around 70 mph or around 2500 rpm on my auto.
like others here said, you'll see most gains with a y-pipe.

and more two cents of stuff: just for the record, i have read posts on here throughout the months about tuners putting the 5th gen stocky on and they are happy as a clam. it looks great, has "normal" db level, and like awsm66 stated, has a valve that opens at wot for greater flow, whilst preserving backpressure for lower rpms. that technology, btw, comes from the Skyline. in fact, you may be able to hunt down a 5th gen muffler if you are persistent and a little patient as some people may be getting rid of those for pure hi-flow types. and it would be economical.
