Thanks for the input, Mr. Snyder. We know you C-10 guys will catch up some day.

I liked the looks of the CSOne and was leaning that way originally, but ended up buying the Leo Vince carbon and am glad I did. I LOVE that exhaust and it comes with the insert already in the box; no additional expense. Installation was a breeze and the look is amazing. SOOO much smaller than that OEM exhaust.
I've ridden quite a bit both with the insert intalled and with it out (takes less than five minutes to change out). Some decel pop under certain circumstances when the insert is removed, but not at all when it's installed. I've settled on leaving it installed on my 2011 as it still has great sound without being too loud.
I'd suggest researching several slip-ons and decide what you like best and go with it. I'm sure most all are pretty nice.
