This is a non-mustang question, so sorry, but everyone here has a lot of knoledge!! I'm building a 318 for my sisters 70' dart. She wants mufflers that are pretty quiet at idle (able to have a conversation), but sounds nice when put to the floor. Any suggestions?? Mabe 3-chamber Flowmasters?? Thanks!!
