Probably. These slip on drop desirable back pressure and alter how the O2 sensors sample at lower rpms as well as altering the intake reversion. That and the fact the bike is already factory tuned lean. Filter is the least of the problem .Question, does Slip-Ons need tuning, a fuel management and a high performance filter? I have a 2015 NRS and want to install the baffled Slip-on by Tab Performance. Please help. Thx
