Bonneville America Forums Forums Technical Forums Exhaust Bubbs & baffles

There's a bike show I'd like to get into in the spring but they require the bikes to be quiet. My bubbs won't pass and I no longer have the stock pipes. I've wrapped the baffels and that didn't help as much as desired. Does anyone know if there are baffels I can get that could quiet the bike down long enough to get into the show?

what the heck kind of bike show requires your bike to be quiet? Is it at a senior citizens home?

I know. They gig you points by testing the db's of the exhaust. You can still get in but lose points for a loud exhaust.

Nuts to that kind of show! What's next, no leather jackets cause it threatens the visiting cage drivers?! A bunch of candy-butts.

Couple years back I called the Bub factory to see if I could get quieter baffles for my pipes - short answer? "no"
Looking over their stuff, the pipes look to be the same, as in, I don't think they offer anything to shut 'em up. IOW, I don't think there's much you can do, short of not starting the bike...

Here's a treatment for specialty spares:



You can insert different sizes of hardware cloth or restrictors to play with the sound.
I'm currently running 1/8" mesh in addition to the 1/4" stuff in the pic.
It mellows things out considerably, although perhaps not enough for your purposes in this case.
