Bgf exspansion chamber

[Greg58]

Has anyone tried the bgf chamber? What kind of power increase did it supply?

its the same one as the one sold by gasbike.net and spookytooth

they make a dramatic power increase down low over a stock muff. Verry loud though

Thats what i thought, does it have a way to put a silencer on the end? BGF has it listed for about forty dollars, I wanted to know about the sound. thanks

i have the grubie expansion chamber. it is loud. i was thinking to try to add a silencer to it. they sell for $5 @ the hardware store.
i decided not to because i am trying to get away from clamp on jankyness.

i saw that pirate is expecting new chambers soon that have silencers built on all once piece. not held together with hoses & clamps.
