Where to buy Fairfield,US Motors,DAP header/expansion chambers

[robo5050]

Hello forum members,

Its been awhile since my last post,so here is my latest;
I have searched online-in vain obviously-for a header/expansion chamber exhaust manifold/muffler for a US Motors US820 2 cycle engine,but have only found pictures of these exhaust components!!

I have uploaded some pictures of US Motors, and DAP race kart
specific exhaust pipes(I will be using them on a Tecumseh 2 cycle that has similar exhaust specs!)so that anyone may be able to reply with any source links for these exhaust components!

Thanks in advance for a reply!!
