Default muffler advice

67 gto with ram air manifolds, 2.25 exhaust pipes, no crossover, need new mufflers (blew one up) I want good sound but do not want a loud drone in the cabin. What is out there that would accomplish my goal?

Pypes' new Turbo Pro is a nice one. Dynomax Super Turbo 17749 or 17747 are nice. 747 its 2.25" I think. Long case. Perfect for a 67.

Dynomax Super Turbo 17749 here. Same set-up as yours, except I do have an x-pipe crossover. You won't be disappointed.

Another vote for ST 17749.

Went with the Dynomax 17732. These sound great, very satisfied.
Thanks for the help
