Guess it all depends on the car and set up! There is a 01ish GT that has flows and it sounds VERY raspy and just annoying. I have had SO many people ask me if I had a V8 in it cause its such a low tone just very mellow. Its far from raspy and its not very loud. I live upstairs and park my car right below my front door if I start my car I can hear it just a low tone a roar almost. But I have heard ALOT of people say that exhaust on the gps just suck! I feel sorry for all the guys who had bad luck but I guess im lucky I picked the right setup and everything for my car! Just like I told the guy putting it on..."If it sounds like **** your re-doing it"! After having it for a year I wanted a more low tone. You can hear the stock cam SOO good with the exhaust system I have so I figure why not let it breath some more and make it a lil louder and so thats why I had him remove it. Im VERY happy with the sound! I had some guy in a Cobra ask me what kind of cam I had and I told him its stock! He didn't believe me! He also said there is no way a 3.8 sounds that good! But again just my opinion!!!
EDIT: I have the boobies so there for my opinion matters more (LMAO)
