Philfowler, I spent a pretty penny but it was worth it. I didn't trust myself on the install, had the shop do it. Pipes, power commander etc. were around $1,000 as I recall.

It definitely helped power, but not a huge amount.

Thanks for the reply Tmac. For $1000, I will have to wait a while, then. I just got mine, and will get it out on the road soon with friends and open it up, see what power it really has.

I am a new member. I had a 2009 C50 that I put 5K on in a year. Traded it for a 2013 C90T BOSS and love it. Added the back rest for my Son to occasionally ride it with me. Handles much different with the wider bars than the 800 but on the interstate it is so much more solid. The wind doesn't affect you nearly as much and it is very comfortable at higher speeds.
