You can start with the three "C"s of good muffler sounds.
Cubes
Compression
Cam
My magnaflows have some drone and some noise but you know its a 350, 9 to 1, and 216 degree cam, just not enough!

Depending on what kind of sound you want out of the car, you could do any one of the following:
1. Dump the stock mufflers and install Magnaflows;
2. Install chambered exhaust system, instead of mufflers;
3. If you just want a 'lopey' idle, swap a couple of ignition wires at the distributor.

If you want it to sound like a Ferrari youre gonna need a flat crank or 180 degree headers. The distinctive sound of a american V-8 comes from the cross plane crank and how the exhaust pulses enter the exhaust system.

Unfortunately living in Cal. you most likely have to keep the cat, as you know on the 82 it flows to a single pipe thru the cat big sound killer. You may want change to true duel set up with 2 cats and good aftermarket mufflers.

You'll need to drop a Ferrari engine in. A BMW V12 fits, so the Ferrari should as well, right?

Have you ever been in a car with an exhaust drone for long periods of time? Gets old real fast... I'll take my '82's quiet cruise all day long. At least I don't have to raise my voice so my passenger can hear me.

Has to be E.O.'d and according to the CARB rules, an E.O.'d cat can't be advertised as "high flow"... of course, anything compared to the stock cat is high-flow.

Double the cams and exhaust valves , add four cylinders and put a hand made tuned exhaust . With capability of running 7K all,day.....and your corvette will sound like that too ....kinda anyway.
Your car is a CSB ....it will never sound like a Ferrari ......it has its own unique sound ....to get the true Ferrrari sound ....

I still run the stock set up but without the cat on my 82 (after 25 years old no more smog test here) and it sounds great to me. I run Corsa & Flowmaster on my C4 ZR-1's and the is sound great with no drone.
