    I know Califorina has some crazy emisions laws. I don't think a muffler would effect it, but I don't know if you can change it to dual exhaust or not if it was originally equiped with a single exhaust system. I'm sure someone from Cali will know.

    Is your truck a Cali truck? If so, don't go dual, not legal. Before my last smog test, I went with a hihg flow cat (don't remember the company, I think Magna?) and a flowmaster one chamber.
