Haven't done a project update in awhile. Finances put it all on hold for a few years. I have my '77-'81 Z28 cat-back exhaust for awhile now, but I only hooked one tailpipe up to the muffler that the previous owner stuck on the header pipe. This temporary setup fell apart last year, and I've got the full cat-back installed now, but I'm still having difficulty getting the old muffler off, and looks like I will have to rent a saw-zall and cut it off. Then add the 2.25" to 2.5" adapter to the 2.5" pipes I have to take the place of the missing catalytic converter. The Y-pipe on the Z28 system is meant to bolt to a bracket on the catalytic converter with a gasket, so I haven't decided yet how to connect the pipe to it.
