Reducing exhaust noise

Discussion in 'Modifications and Projects' at netrider.net.au started by dale, May 6, 2008.

  1. I need to make my pipes quieter for the sake of a roadworthy. Any ideas on what would be best? Also, does anyone have any photos of what an exhaust spud/bung looks like as I may be able to make a couple which would do the job.


  2. Steel wool and a coat hanger. But only do it around the corner from the testing station. It catches fire and ejects from the exhaust system!
  3. put the baffle back in.. :LOL: :p
  4. Maybe ring around the wreckers and see if you can borrow a pair for the test? Otherwise maybe post in the wanted section. I'm sure a few Storm owners have kept original pipes for just that reason..

    Good luck!
  5. Hotcam. Are these inserts to make an exhaust quieter? Have you seen/heard one in action?
  6. yes and yes. These are the typical thing supplied with hot race
    pipes by aftermarket exhaust manufacturers to quieten their exhaust
    for road use. Typically they say will reduce approx 105dB to approx 96dB
    depending on the bike. A similar design might work for you.
    Do an internet search for "dB killer" for more info.
  7. perforated steel plate, rolled like a cone shape and stick it in the pipe. Mine was 102db and needed to be 96db and this did the job.
