Was thinking...(insert joke here)....seems like the factory, all factories, sort of missed an easy opportunity to exploit the possibilities of exhaust systems, mainly mufflers, back in the day.

If you exclude different exhaust tips, and talk about dual exhaust systems, there were very few differences in the systems in most cars. The AAR T/A cars were a big exception, as was the LRE......but beyond that.....

Why not build the Road Runner and Super Bees with Mufflers that we’re still noise compliant, but just a bit louder to appeal to the youth crowd. Ditto for the chargers, and maybe even the E bodies.
Maybe some factory headers on a model or two? Maybe even re-rate the HP and up it 5 hp in a case of two.

Just seems like exhaust systems didn’t get much attention.

I’m bored.
