 expansion chamber parts
Hi all
I am looking for tapered tubing to build my own expansion chamber.
I am a skilled welder / machinist, and want to try my hand at building an expansion chamber for my 121cc 2 cycle suzuki. I cannot seem to find a source for the pipe to make the diffuser (megaphone), and baffle out of. I have plenty of streight pipe to make the header, body, and stingers out of.
Does anyone know of a sorce to buy tapered tubing with angles of 7-9 Deg for the diffuser and 18-22 Deg for the baffle?
I have been looking for a while now, with no luck any help would be appreciated
