The exhaust on my 442 was beginning to look like swiss cheese due to rust forming on the inside. I bought the complete Walker factory replacement exhaust from amazon.com.

You can look the prices up on Amazon. I think it was around $450 with the converter and that included all the clamps and mounting brackets. The only pipe that is salvageable is the 90 degree pipe that is on the inlet side of the converter. The screws are hopelessly locked to the converter and would need to be cut off. The rest of the pipes are toast. They look fine on the outside, but the wall thickness is paper thin from rust.
The Walker pipes are built well and is a true bolt-on system. I did not even jack the car up to do the install.
The Walker Quietflow mufflers sound about the same as the factory mufflers did. I will see if I can take a short video tomorrow.
You can see the Quietflow mufflers are a "straight thru" design like a glass pack.

I seen this post but didn't see a pic of the exhaust side of the cat. I'm replacing mine with the exact same one, but I thought from the factory, they had spring bolts for the "donut" style seal. Is this correct? Or was it just two bolts torqued?
FYI, I recently was searching Summit and Jegs, and low and behold, there is a perfect fit bullet muffler replacement that fits right in place of the stock ones. It is 2 1/4" all the way through, and gives it a nice deep tone without making it raspy sounding. The reason I went looking for these was that the stock muffler didn't clear the trailing arm brace at the front of the lower control arm. I'm glad I did. Much more clearance and a better sounding car. Funny thing is, this bullet muffler is made by Walker-Dynomax. 
Here is a photo and link in case anyone wants to do the same.

what other mufflers do u guys recommend that sound better then stock and fits rite into this set up?
I always thought turbo mufflers sounded good with Olds motors. I had true duals and turbo mufflers with headers on one cutlass and my 307 powered 442 has factory looking exhaust with turbo mufflers and it doesnt sound half bad. Its loud enough to hear when you start it up in the morning out front of the house but not loud enough to piss the neighbors off.
There are two systems that sound pretty good..The Walker replacement system, and the Hooker Super-comp system... The hooker one must be bought for a Gand National, but they both fit the same.. Same cat flanges, so its a direct fit cat back type and even comes with a "test" pipe to replace the cat with(for any that dont have to pass smog tests), but can bolt right onto the back of a stock one...there is one more I found after looking, and thats the Flowmaster American Thunder kit, but that is what its name implies, LOUD.
One major difference, only the Walker system actually looks stock.
The Flowmaster one is only cat back, and tailpipes come out under the bumper(Monte Carlo style), and the Hooker lit has mandrel type bends(no kinks).
...But yours looks great under there, and it must even feel better in the skinny pedal...
