Get the type with the original style fluted baffling , not the perforated tube type - the difference in performance and sound is amazing.
But which are the type with the fluted baffling? Who supplies them?

Feked do a version with the flutes, but you have to check with them as they sell 3 versions on the same listing to make sure the version you pick has the flutes.

Do flutes refer the angled holed baffle plates just in from the rear of the silencer??Feked do a version with the flutes, but you have to check with them as they sell 3 versions on the same listing to make sure the version you pick has the flutes.

No, a proper fluted peashooter is fluted on the central tube, most are now a perforated tube and do not direct enough air into the outer chamber and so too noisy.

kommando & trident Sam,
Thanks for the heads up regarding the construction of the central tube. Do I assume correctly that these flutes look like miniature louvers? Do all the flutes face forward? Or do the ones in front face forward and the rear ones face backwards? Just wondering how the air directed from the central tube into the outer chamber is exhausted? Is there a photo available showing this feature?

More or Less Quiet Peashooters
I've got some black caps that came on my '75 that I'll let go cheap, if you want. Cj

They all point forward so they scoop air from the exhaust gases and force it into the outer chamber, I will check the one I have tomorrow but from memory there are no reverse scoops at the back of the silencer, so air exiting the last flutes will go forwards further breaking up the exhaust gases wanting to escape.

According to AN, the "outer chamber" would have contained "sound deadening material" originally.

Aahh! AN supply the 'original' peashooters... I had missed that.
Thanks L.A.B.
