So currently my 07 silverado with 4.8 v8 has 1 flow master super 44 (black) muffler turned down before the axle. It's ok but not real loud compared to my old truck that would set off car alarms lol and I miss those days. I have been wondering if anyone has ever mixed an exhaust. I'm thinking of keeping the 44 with the turn down but dualing the exhaust with a flow master 40 and have it turn out in front of the rear tire. I have no idea what that would do and would like to get some opinions on the matter. My old truck had a mild built 350 dual flow master 40s turned down and when fired up would set off car alarms lol but in all reality it wasn't horrible to drive daily so what's your views of this freak show exhaust I'm thinking of?
