In today's world motorcycle sound requirements are not to be ignored! Big City Thunder has addressed these sound issues with our new patented Quiet Thunder Monster baffles. Our new cone-style Thunder Monster baffles are quieter than our original Thunder Monster baffles with a rich, deep tone to the exhaust note. Our latest breakthrough design dissipates sound energy to reduce the db levels. The new Quiet series also increases rideability and mid range performance.
We call them Quiet Thunder Monster baffles. You'll call them the best decision you ever made for your bike.
The most accurate way to determine which size baffle will fit your exhaust is to measure the inside diameter of your headpipes about 6 inches from the outlet.
