1st time I've seen it, but ...
'Constructed using a stainless-steel shell, interior core tube, and high temperature stainless packing wool, '
If the packing will survive aircraft use, it will be a first.

Group:
I’m curious if anyone has ever experimented w/Racing Beat’s Power Pulse Presilencer to quell the nasty roar from older 13B engines?
I soon hope to begin work on my 1989 13B exhaust system, and I’m already planning on a a belly mounted muffler of some type, but in reading the Racing Beat information concerning their “pre-silencer”, they make it sound like it is an effective way to tame the nasty supersonic pulses from an older 13B, and thereby increase the longevity of the muffler unit.
Any thoughts?
Thx.
