OEM exhaust cans and systems won’t win a beauty contest these days (and rarely did they in the past), they weigh a lot more than the aftermarket counterparts, sound crap and you never reach the bike’s full potential with them. Whatever the reason is to change your end-can or the whole system, removing the exhaust valve will leave you with the dreaded FI light. Install the ESE to take care of that so that the FI light will come on only when it has to – when there’s trouble with the engine.
