| I’m thinking of upgrading my exhaust from the flow master original 40 to a super 10 now knowing that it’s louder but not the loudest as the outlaw muffler that they sell , I’m worried about noise complaints I’m gonna have a muffler shop put it in and he normally knows what he is doing . The truck is a 2003 f150 4.6 liter engine has all stock CATS on it nothing has been jacked with it except for the exhaust kit I put to make it dual. It’s. Fake dual one inlet with two outlet muffler. Any advice or help would be appreciated. | |
