Who's using Cone Engineering 4-2 Quiet Core Mufflers on CB500/550?
« on: September 10, 2013, 02:12:49 PM »
If you're using these mufflers, what can you tell me about them?  Are they "quiet"?  I would love to see some detailed pics of how you have them mounted and how they look on your bike.

compared to the 12" open reverse cone, yes, they are quiet, with a nice growl.  this one is on my 750K8
you'll need to clamp them, and might want to weld a mount tab as they have some weight to them...

Here's the 2-1 Quiet Core I run on my own bike. I'm running 1.50" SS header to a 1.75" outlet 2-1 collector.  I have loads of bottom end so when leaving the house I can click it up a gear high, drop the RPM and be extra quiet.  I have geared on the high side as well since these XS motors vibrate like a paint shaker!

There is now a whole series of videos with each different muffler all running on the same bike so you can compare them: http://www.coneeng.com/product_videos.html

Did you weld the tab on yourself Rob, or did you find a local shop to do it for you? Sounds great BTW I will have to hear it in person someday  ;D

This isn't the Quiet Core but a mounting example.

Flybox the muffler sounds great, but what's the source of the other racket. Do you have an open cover Ducati dry clutch in that 750?
