I wanted to know if anyone has used or have seen this exhaust on a bagger by FBI?How does this 2-1 compare in performance with other 2-1's such as fat cat,rineharts and oters?

 

I just bought one and love it. I bought mine from ebay and got a heck of a deal on it. It is actually freedom performance exhaust that makes it for FBI. I have not put my bike on a dyno since I installed it, but seems better than the true duals I had before.
