Made some track day silencers

[Brummmie]

Made to fit my 3" tailpipes, they slide over and then clamp.
Its a 2" baffle that reduces the outlet from 2.5", plus the wadding etc inside.
I have made them repackable also.
From my crude iphone noise meter idle goes from 86db to 78db.









Not pleasing to look at but hopefully means i wont get sent home for noise!

I was considering something similar.
A slight tripping hazard and dare i say wheelbarrow like but nicely engineered.
Be interesting to get the result of a proper test at 3/4 revs.
You do tell them you go to 8000 dont you Paul?
