The real 273 HP exhaust sound

Nice sound!! Nice car!!! Thanks for your response. I am planning to go to the nationals this year and hope to hear some in the flesh. The exhaust on my Dart is in good shape and replacing the stock muffler with a Dynomax Turbo
helped. Sometime since 1966 the crossover pipe was replaced with a 2-barrell
pipe so that will have to do until I can spend the $750 for the proper system.
