Today I deleted my resonators, tomorrow I'm adding Flowmaster to my 16 RT Plus. I am looking for old muscle car rumble during idle as well. I'm torn between the 44's and 10's. I don't want to be obnoxiously loud but want to have a rumble and growl. I have the A8 Auto, I know the 10'a are the loudest but I also don't want my wife and kids to not want to ride in my car. Would the 44's be enough or should I go with the 10's.
