  1. That inner tube is SOOOO beautiful. It’s a pity that isn’t on the outside. The sound difference you achieved is remarkable. You are exactly correct. It’s not so much the volume of the sound and that very irritating rumble.
    Thank you for sharing this YT.

  2. I really like the design, with the slit cut then punch. If I do it, I’ll reverse the flow so it’s directed towards the fiber glass packing. I feel like it would be quieter.

  3. Growing up we called it glass pack not glass back. Or am I hearing you wrong or was we wrong growing up? Nvm, I see at the end you put glasspack.

  4. You had your air flow in wrong direction the dents you had in pipe are ment to catch the flow of air. You have ya muffler on backwards !!!
