I ride an '03 F4i with a C2 Two brothers slipon. I'm looking into getting into racing and making it my track bike. I want to have a full exhaust system and wondering where to just buy the header for the Two Brothers. What are some websites to where i can get it at? Thanks in advance.

 

umm i have a C4 two bros on mine, and there doesnt seem to be a two bros header system. i think akrapovic is the best bet for a good full race exhaust.

 

Yup you're gonna have to sell the Two Brothers (S/O) pipe & buy a full system

 

I will help you out and buy your slip on when you upgrade. Let me know GMC2000@eatel.net

 

Damn well alright i'll let you know the outcome. I was hoping they just sold a header so i could make it a full system.

 

That would be TOOO easy, and then no companies would make any money

Instead....you have to spend more $$$$ on a different full system
