I got a Flowmaster
 

The truck I just bought has had exhaust work done. It has had the convertors removed and y's into one pipe. It has a single entrance dual outlet Flowmaster. How can I tell What series it is. Also how much sound difference would it be to go with true duals. Would there be a performance change by doing this. I could also make a "X" or "H" pipe as I have acces to a bender and pipe. This truck runs strong for a 302 auto in a truck. It really talks around town but I cant hear it on the road if the radio is on. I mainly want to know what series it is or if there is a way I can tell.
