I inquired if he is manufacturing the exhaust for the RD 400-350's and the answer was not yet but if there is enough demand he will produce them.

the company is Hell Fire Expansion Chambers

Seems he even gives them the Mop & Glo treatment, or something similar.
"Pipes sets come finished in a protective wax sealant"


And if you don't like your neighbors there's a straight stinger version available.
