When I first got my C3 20 years+ ago the very first thing I simply had to do was
A. buy a pair of headers
B. buy a pair of mufflers.
As you have already noted Cherry Bombs sound too strident. TBH, I had always done this with every car I've every owned, from old school Mini Cooper glass packs on 3.8 Jags to Thrush turn-o-lock glass packs and header mufflers on Yank V8's. (

I had used Simon's mufflers - made for years in Denmark or somewhere similar and marketed here in the UK as Jetex -

Available in polished stainless or satin black mild steel they are an absorbsion tube muffler but always used ceramic wool rather than glass fibre which wouldn't oil or coke-up and end-up getting really unpleasantly noisy. I had mine on the Vette for at least 10 years with no corrosion......they did get a little louder after a time.
If you want to replace your existing mufflers on a visually like of like basis simply search for the correct tube diameter and case length approximately the same as your existing mufflers (perhaps even a little longer if you want) and get your favourite exhaust shop to make-up the required brackets and tube bends to fit them.
Bonus is they will look stock, even sound a little 'softer' on idle than stock but progessively get louder as you hit the gas pedal.......never loud enough to attrack the old bill, but in a really nice way without the drone of some baffled mufflers. Remember that a larger (even oversized) diameter pipe will always sound deeper.
