CinKo Echo CS400 Exhaust Mod

This is a quick video on how to do a muffler modification to an Echo CS-400 Chainsaw.
This in conjunction with the carb adjustment mod allows a big increase in overall performance.
Make sure you have done the carburetor mod prior to doing the exhaust mod. If you have not yet done the carb mod, I have a step by step "how to" video in my uploads.
Please note, modifications to pretty much any engine or emissions regulated device on pretty much anything in American will most likely void or affect your warranty. If you are worried about warranty coverage, you can always buy another exhaust off eBay (running about 18$) and mod that, allowing you to swap back and forth.
Cheers
