About 2 years ago a fantastic popping sound alerted me to the fact that the entire contents of my righthand side Ralph Elliott modded silencer had launched itself down the A38!
So I rebuild them from scratch myself.
I found the best sound and performance came from packing them with stainless steel wool pads (like Brillo Pads).
I used stainless steel perforated tube inside and machined aluminium end caps from solid billet on my lathe.
Sound is lovely,louder than standard but not as loud as the 'Ralph Elliots'.
I would recommend the Elliot nodded silencer mine were 3 years old before the rh one launched itself.
I hope that never happens to me.
I did use 8 bolts on each machined cap just to be sure, as the pressure inside the muffler must be bery high (especially with resctricted ends using a db killer).
True the db killers just use 4 of them, but the akras used just 3... should be fine (crossing fingers).
Kodo...kudos on your skills & the excellent mod whisperdancer
