A friend is about to buy a T-4 exuast for his TTR-125. Does anyone else own this system? We will be ordering it. What jetting do you run with this system?
Will it need a new header?

Yes, we are running the pipe on one of our TTR's. We went with the 112.5 mainjet (Mikuni Large Round). The pipe is a complete system - header and all.
