I have a Magnaflow dual tip muffler with no res. Its nice and quiet in the cabin during curisng speed but when you get on it is desectly loud.At idle it has a deep enough tone. Its def noticable outside the car but in it its not bad at all. i love it and my friends like it so im happy. Go with magnaflow you wont regret it. If you want a sound clip let me know ill make one for ya.
