Jason:
Where did you pick those up? How much?
You can buy direct from here:
http://www.cfrmotorcycles.com/ probably pay list price and I think bikers image is a dealer but they never called me back after leaving 2 voicemails.
I bought a like new set from craigslist and had em on for one day. Initially , I liked the sound but the tune of my bike did not match well and lost a lot of low end response. Read a lot of posts about difficult to tune and after a two hour ride I decided they were too loud for me and I decided not to put the effort into trying to get them tuned and sold them almost instantly , losing 50 bucks in the process.
They look amazing and the tone of them is pretty bad a$$, but i gotta have some throttle response and I like to listen to the stereo every now and then as well.
Some people put some baffles in the pipe to help out a bit, but I decided not to take the time to try that. Hence the reason for my earlier question
