Flowmaster 40 dumped?

so i had a single 3" flowmaster installed no cat...this is in a 1990 dodge ramcharger 5.9 l 360. Im loving the sound but to hear it i have to gas it and the truck gets bad gas mileage. Anyways it was installed turned to the ground at a 45 on the side pretty much where the stock exhaust was. Im wanting it too be louder without changing the tone, can i cut the tailpipe off after the muffler right before rear wheel and dump it 45 or so?, will this make it louder and still sound nice and deep/throaty?
