You have the 5.3 or 6.0? I found a lot of reasonably priced ones for the 5. . But each one I found for the 6.0 was about 200-300 each
5.3. Was a flowmaster unit. I think magnaflow has 6.0 stuff but idk what the prices are off the top of my head

Surprised you still have your stock muffler on.

I believe it is a giant flopro muffler that is dual 3" in/out. Never looked close at it but I like how quiet it is so I don't plan to change it even if I'm losing 10hp or so. The PO had a magnaflow dual 3" in/out and said it droned terribly. He gave it to me but I think my neighbor stole it lol.
