    TTR 230 T-4 Exhaust (Jetting and Header)

    I have a TTR-230 which i just installed the T4 pipe on yesterday. I was talking to someone who told me that changing the jetting would improve the performance even more. I know this is true, but is it really worth it? Also, is there a way to get a new sliver header for the pipe? This isnt a priority but because the T4 doesn't come with a header so you are required to use the stock header, and it looks a little tacky where the pipe joins because the T4 is silver and the stock header is black.
