As far as an intake goes....the best performance wise is a vararam, however it is cheaply built. besides the vararam, all the others are about the same. Stay away from the e-bay bullsh*T,(hot air intakes) and pick up a T.B from Fastman, was running catless for a while, but put them back on, and noticed more torque. Cams are a good way to go also. Like I said just Pm me, almost got enuff money for my Procharger...lol

 

The muff is a dual 2-1/2" in/out Magnaflow.

 

It looks like you've got a heckuva truck there! I don't think I'll be taking it too far. I really just want whatever add'l performance I can get while chasing down a few extra MPG's. Us ol' fart types get like that.

 

OK, so now I've got the exhaust on it, and I'm getting the "PO430" code.

I went ahead and put on the Airaid MIT and put the superchips "91 octane" tune on it, still the "PO430". Any suggestions?
