white brothers way too loud

Recommended Posts

after reading the thread on re-installing the oem pipe, i reallized i was not the only one who thinks they are too loud. my question is, is there any way to quite the wb R4?

it has great power but it is unconfortably loud. any options/ alternatives will be greatly appreciated by me and my neighbors!

Check the whitebrothers website. They may offer a silencer insert. My powercoreIV went from 100+db to 88 with the silencer in it. Not too bad of a power loss. Yay :cry:

The more you've opened up the motor the more you'll notice the plugging up of the pipe. A stock motor with a pipe and a quiet insert will probably runn ok, maybe some slight jetting changes. It's all about air in, air out.
