The sound measures 98db at 1 meter from tail pipe running 2/3rds revs.
As per MSA blue book.
To remove baffles:
1. Remove tail pipe and clamp in vise, gently.
2. Using a 38mm hole cutter and a 1 meter 3/8 drive extension mounted in a cordless drill, remove baffle. This can take about 20 minutes as it is 1.5mm stainless. Keep the cutter lubed up.
3. Refit tail pipe fire her up and smile!
Note, I used 2 cutters one per side as they blunt quite quickly on the stainless.
