I run a magnaflow 12219 muffler. Great sound when on the gas and zero drone on the freeway. Just a 3in/3out with a 14in body and 20in overall length.

especially with no cats, the 22 is the one you want. your truck should have offset and center inlets/outlets. verify and if so, best to get the magnaflow 22 with same inlet/outlet that way it is just cut and weld as a perfect replacement.
good luck, Rob
