I just put in a true dual with 18" sweet thunder mufflers and the car is loud as hell (too loud for me!!). I'm thinking to replace the mufflers with either 14" Hooker aerochambers or Magnaflow.

First, which one will be halfway between the Nascar loud that I have now and a quieter exhaust? I don't want something that needs to be revved like crazy to hear......

Second, i see tons of Magnaflow mufflers on the website....which one is best for my application? (Oval, round, 14", 18", different case sizes???)
