Pete - I'll get this started, albeit not a good comparison. A friend paid $9k for a complete NOS exhaust system for a '70 6pack Challenger. I can tell you, it won't be cheap. Altho there are no mufflers, per se, involved with a chambered exh system, the desireability of this one year (partial year) exhaust system from a collectors stand point will drive this price up.
