Have just purchased a full race system with a carbon oval can (great).The surplier of the exhaust told me that i would not have to have any remapping done due to the fact their system copies the original systems curves (power curves).He did state that if i felt unsure then i could remap for peace of mind.Have any BUSA owners fitted this system and did they remap?.The bike has no other engine mods,any info would be helpful.THANKS PEOPLE AND KEEP UP THE GOOD WORK DURING THESE NEXT FEW MONTHS AS THE WEATHER WORSENS.
