Installed EHS big 3 a few weeks ago. My family is bitching and I'm sure my neighbors are pretty pissed off by now. Where can I purchase the EHS quiet core? I am not having much luck on the EHS website, should i just call them?

Just give Eric a call at EHS. The quiet core is $25.00 and has it's own spark arrester. Mine was sound checked by the FS and tested at 92db. Remember to lean the fuel mix when running with the quiet core.

No quiet core...
Green = 3.5
Yellow = 3.5
Red = 3

With quiet core...
Green = 3
Yellow = 3
Red = 2.5

No changes are needed to the other 3 efi settings.
