finally made up my mind and had a flow master put on
Ive had my 14 black express for a month or so now. Finally goy tired of the stock rumble.
So I dropped the truck off yesterday to have a flow master put. I was nervous going to pick it up after work. I started it up and I couldn't be happier its got a great rumble on start up and idle and isnt to loud in the cab.
My buddy following me said its nicr and loud out back which is what I wanted. It has a small amouny of drone in eco mode in the city but not to bad on the hi way.
I went with a simple replace of the stock muffler with a 40 sries flow master.
