Shouldn't need to rejet just for slipons or swapping out the OEM pipes entirely. Stock mufflers mute the popping due to re-routing the exhaust with the baffles and pipe configuration. Like I said earlier, a little adjustment of the PMS
might be needed, but not usually. Once I removed the AIS
99% of the popping stopped for me.
Rejetting is necessary when the air intake is opened up, like with a BAK
, or drilling more holes in the stock airbox, etc.
