Out of the blue, my light came on yesterday. I went to autozone and they gave me the code. I messaged my mechanic who said it's a bad cat. He said it costs hundreds to replace, then mentioned an "alternative" option for repair.
Forgetting the alternative for now, how do you replace the cat in a 5.3? How do you find compatible units? Is it a cut and weld in place? I've seen some "bolt in" pieces that look ready made for the truck. I have never played around with exhaust at all. The V8 TB sounds really good, no need for custom exhaust (other than a resonator delete).
