    hi, very soon i am about to purchase a full exhaust kit for my 07 cr125. i am wondering if i should go for a pro circuit works expansion chamber with a r-304 shorty or is there any FMF that would be more suited or just better?
    i have a new jetting kit that has given the bike a bit more power but i wouldnt mind a bit more edge to beat my mates.
    i ride on pretty much anything but when i rider tracks i would like some quick power out of the corner.
    cheers in advance
