Pulled out a long stored 240z couple days ago, to look underneath, noticed the paper tag part number still intact in front side of muffler.     It is painted black, so it definitely has been replaced at some time.
      Curious to opinions concerning saving the   Paper tag or let it burn off with heat over time .         Basically asking if ever in a judged show, would it hurt or help in “stock” class?

I would carefully remove this tag and put it in a clear photo grade plastic sleeve for future reference.

All the information a judge would need, if he bothered to look, is embossed on the muffler itself.

The exhaust system on my car is all NOS with this very same muffler.  As rare as this is, I had the

whole exhaust ceramic Jet-Hot coated in the original bare metal finish to preserve it through

a life's worth of heat cycles.

Unfortunately trapped moisture will typically corrode these mufflers from the inside out.  No amount of external protection will help stave off its demise from within 😟

Hi Dan, yours is super! I really love seeing the original muffler and exhaust system, even you put NOS into your car. The Long black/chrome tip is just right for our car and the front tube is an early type which makes me feel hand crafted pieces. Those parts must have been so hard to come by, harder than D hub caps I think. Even the green BAT 240Z doesn’t have the whole system.
