Long story short, I need to replace Cylinder 2 and while we're in there, the muffler appears to have lost all of its internal baffles so it and the tailpipe are candidates for replacement. Where should I look for cylinders?  I can Google and have found a couple of power assemblies around $2000 but I imagine someone here knows of a better way to source a decent setup. Similar for mufflers.  I'm looking at AWI but I'm not 100% sure which muffler to get for my IO-360-A3B6D.  Slip Rib or B
