I have a 92 Sonoma 4x4 Std. Cab 4.3L(Z), and my muffler and tail pipe are shot. I was wondering if anyone could suggest a cat back system that would bolt up in place of the current system. I have looked around on the web, and I seem to find a lot for the 4x2 s10/sonoma, but the 4x4 seems to require a different kit. Does anyone know of a kit that would work on my truck without having to weld, etc? If not, what mods need to be made for the 4x4? Does not necessarily need to increase performance (although that wouldn't be a bad thing), but just a resonably easy replacement for a DIY'er.
