I put together my own 3" cat-back system using information from this thread. It's a really good thread if you haven't seen it.

Technically, it all can be clamped together so there is no need for a shop. I have a welder so I'm going to weld most of mine and install some flanges so I can take it apart if I need to.
GMRedline, did you ever get this system installed? Curious to see how the y-pipe lined up. I'm getting ready to do the exhaust on my '98 Z71 and want to do away with the factory 1 7/8" garbage. 2500's around here with usable exhaust don't exist, so I'm working on other options.
