Hello,

Since I ride in an area with many houses around I want a quite muffler. I was wondering what the db's are for the stock 2000 400ex muffler and when the spark arrestor core(bolts off) is removed. And does anyone have db levels for all the 400ex mufflers?

Thanks for you help.

 

you cant remove the spark arester, but the baffel you can. Expect over 105DB with it removed. I only know that the stock system is quietest
