Is there anyone out there with a 4.2 that went from the OEM setup to a couple highflow cats and a nice muffler, leaving out all that other garbage?

If there is, itd be cool to see some pictures of the process and any customization you may of had to do.

Im going to tackle this in a couple weeks and im fairly confident I can get all the pieces in place I just am not a welder....do I need to weld the pieces or would clamps work just fine?
