I have had the ggb mountain can on for a year. That ended when I gave a guy a ski pull with a can louder than mine. I took my can off after that and love it. Went back to stock. I don't mind the stock sound and can hear myself think.
Thinking about getting a "Thing" for my '14. It has a cooker built right into it that will cook your lunch in about 20 minutes. The sledshed sells them
