Once again I received great survive from these gentle and great work to match.
These are very hard working gentleman who take questions all day long about drone, raspy sound, growl, back pressure and never seem phased by the repetition of questions.
I have a 2014 Dodge Challenger R/T classic with magnaflow mufflers at the rear and muffler/Resonators in the middle still attached.
They advices me to get more growl with minimal drone that I should remove the center units and stick with the Magnaflow ovals. (I was contemplating Flowmasters)
In the end I was very pleased they warned me of some drone but it seems minimal.
I am contemplating Dynomax 38490 vt zero drone system. If I do go the the Dynomax system I will definitely be going back to Perfomance Muffler
Thanks a lot for answering my questions and having patience for me! I'll be back
