273 stock , what mufflers for duals ?

XLERATOR® STAINLESS STEEL PERFORMANCE MUFFLERS | AP Exhaust Technologies
A friend of mine in Houston has these AP mufflers on his 65 Dart 273 with 2-1/4 duals to the rear bumper and it sounds amazing. Nice deep, throaty roar but not real loud either. No annoying noise inside the car either. And the price was very reasonable for him. Wish I could get a recording but the owner hates phones and such so I know he won't record it for us.

Agree with grimreaper. I used these on my Valiant when I had the 273 Commando in it. Great sound!
