OPINIONS ON EXHAUST SOUND

I have a simple recipe for a quiet non power-robbing exhaust system.
Get the right size thru tubing for the engine combo (no 2 1/2 tubing necked down inside the muffler, to 2', or 3" necked down to 2 1/2) and get the biggest, longest muffler of your choice (triple pass, straight thru, or chambered) that will fit under the car.
Which muffler type you choose will determine how it sounds.
