Answer

Glenn my boy, do we have an answer for you! Quiet baffles are available for the Fat Cat systems. They are involved to remove and install. Enthusiasts without the ability to do this themselves should have a competent mechanic complete the installation.

The team at Zippers should not have any problems with this update.

Enthusiasts have reported back to us about an increase the HP and torque by a few numbers after installing the new quiet baffle. The sound is reduced approx 50% over all. Retuning has not been an issue if you are changing from the standard baffle to the quiet baffle. This is because the cores are basically the same for the two silencers.

The baffle for your bike will need to be ordered through us because this is a special order. Our order hotline is 817-834-8961.

Please note, D & D will not warranty any systems and or parts that may be damaged through the removal and or install of the new baffles. And we do not replace them here at our facility.

Question: Why do mufflers blue?

Answer:

Chrome turns blue due to oxidation at high temperature. If you look behind our heat shields you Will find bluing on all of our headpipes due to exhaust gas temperatures above 1000 degrees F. The heat-shields provide an air-gap to reduce conductive heat transfer, plus chrome plating to reduce radiant heat transfer. Also the billet clamp mounts and the heavy gage of the heat-shields themselves help prevent hot spots. Our baffle designs incorporate a variety of protective chambers, sealed exhaust pathways and heavy gage materials to protect the finish.

Bluing of heat shields and muffler housings is caused by excessive heat generated from improper fuel mixture, ignition timing, or a combination of the two. Rich fuel mixtures burn inside the pipe and lean mixtures raise the exhaust gas temperature .
