twin 2inch on r1

Discussion in 'Modifications and Projects' started by eb six on boost, Jul 26, 2007.

  1. hi, ive finally just got my 2002 r1 which already has the same dime a dozen yoshi muffler.
    what im planning on doing making a twin 2 inch s/s system which will run under foot pegs and up under the tail in to a single 5inch can muffler with twin entries and exits.
    i dont want to hack up the titanium headers to remove the exup, are pre 2002 r1 headers s/s????
    will i have any big issues with anything by not connecting the exup???

    i have power com ready to fit also

    im not after more power, just want it to sound like it should and not be like everyone else.

  2. You'll lose a heap of midrange torque. You'll probably also need to modify the electronics as the ECU may not like it.
