Ok. I'm about to move back to California. I have a 92 K3500. I need to stay smog legal. I know the 95? and later HDs models have dual cats, and exhaust up until the muffler. Which I've read GM did an amazing job of designing. To stay legal would I be better off buying a replacement factory setup for the later model. Or just fabbing up a new one. I know I can only have a single exit. But I'm not to worried about that. The crimped bends and small single diameter in front of the can is what really bothers me.
I'm also looking for some 50 state legal headers for the big block. Inexpensive please. But not cheap.
The goal is MPG(yes I know its not a prius). But at the rate she drinks gas. even 0.5 increase is going to help the wallet. And a little more power.
I also plan a cam upgrade. And a little head work. Trying to get the compression up a little.
