I am unsure as far as bikes go but I will look into it. However basic engine operation…
Free flowing or even accelerated exhaust only effects the motor if it’s backed up or requires back pressure for efficient engine operation.
If its restricted it’s like inhaling from a pipe and trying to exhale from a McD’s straw.
Accelerating the flow only lets you get out the exhaust faster allowing the potential for more to get out. If you remap the fuel and air to get more power you will need a free flowing exhaust. If not.. well you wasted a lil bit of money for cool aesthetics of wrapped pipes and maybe keeping the heat off your legs.
edit: hope that made some sense…I typed it during class and trying not to get caught….shhhhhh
