lastrights, when you added the 3"in SI/SO Magnaflo cat was that only change you made at the time and was it noticeable? That's the route that I'm looking at taking.
BTW I saw your vid. That truck has a mean snarl to it. It sounds cool.

no pic, but I did install one with an O2 bung so I could run my wideband out of the original O2 bung.
I believe it was Magnaflow P/N 99039HM. But you gotta know your exhaust pipe sizes when you order.

I put the direct-fit Magnaflow from Summit Racing. The fit was great and I think it was about $200. The only thing it did not include was a clamp to go from the Cat to the factory exhaust.
