I'm looking to add a new muffler to my 07 300c. the one i have on it is stock and it has a nice little sound when i first turn it on but then it goes away pretty much instantly. i want to hear my car accelerate and i want to hear it when its idle, but i dont want to go get a million tickets for having an exhaust that is to loud. so please somebody help me find that happy medium. I also am trying to find a catch can for my car what is the best one you guys have had experiences with? Thnx in advance for any helpful tips.
