I'm approaching time to fish or cut bait with my intermediate muff - the one over the right half shaft. The resonator parallel to the dshaft is okay, and the rear muff has had holes which I fiberglassed years ago. The glass is holding well enough.
We read that the Bosal replacement for the rear muff is out of stock everywhere. I suspect it will not be seen again if it was a coupe-specific item, unless someone comes upon a gold mine of old CS bits. Is there a Walker or Magnaflow counterpart/substitution that is relatively stock in size and angle? Not ready to spring for full stainless.
We read that the intermediate muff is commonly removed and replaced with a straight pipe (more accurately a curved unit) that goes either over or under the half shaft. I think I'd prefer the original routing over. Supposedly the intermediate muff can be thus replaced without noise consequences.
This gets me to thinking: what's in a muffler anyway? All the old cans I've taken off beaters I just hurled into the weeds. I THINK they consist of a can with perforated straight inlet and outlet pipes, and some rock or mineral wool between. Has anyone gone in for a look/see and can they report?
