k 2500 with 454

Hey, I ordered a new 1997 K2500 4x4 with 454 and 411 gears. Still have it and it has only 29000, original owner, miles. But the question is: i want a muffler with dual inlets and dual outlets for this truck. From the factory it came with dual inlet pipes and dual cats but a single outlet. I just want to add a second tail pipe. I cant find any listing on the truck anywhere for replacment exhausts. Looks like I have the only truck made like this, lol. Thanks

try an aftermarket compeny im sure the will have the mufler and pipes you need to make it a true duel truck
