Looking to put different mufflers on our '17 EB-auto Mustang.

Found a nice sounding muffler(s) from Ford performance (M-5230-M4TCA). Best price I can find is $940 for 2 mufflers !!! Incredible. Anybody know of replacement mufflers that are not raspy, drony, or obnoxious that I won't have to give up my first born male child for?

Also thinking of putting a different down tube on the car. The replacements seem to be a 3" pipe that necks down to the OEM 2.5" pipe. If the new down tube...
