I am getting a slip on exhaust for my 400ex and i am debating between the FMF powercore4 or the FMF Q4. Do you guys think its worth an extra thirty dollars to get the Q4? I also saw the Big Gun eco system but I dont want a poorly built exhaust.
when i bought my 02 it already had the Motoworks SR4 race series on it. i have owned different exhaust and this one surpasses everything else. do some research on it and check the stats. i also think it just won the pipe shoot out
