Me and an older man at work were talking, he's huge into trucks. He told me hes got tons of mufflers at his house and he'd bring some to work and if I wanted them just take em. Well he brought in several Flowmasters, but were very rusty, under the flows I found 2 almost new V-Force mufflers.. After some research it seems as though some people call it a knock off Flowmaster 40.
I am going to put one on this weekend and see how it sounds, I will try to get a sound clip. They are only 2.25" and coming off a 3" I will have to get some reducers.
