WARNING
Please note that certain aftermarket exhaust systems may not comply with applicable California
laws and regulations, and may therefore be prohibited for use on California highways or roads, or
on roads or vehicles otherwise subject to emissions control requirements.
Akrapovič exhaust systems for automobiles and motorcycles mounted downstream of the catalytic
converter (also known as “cat-back systems”) are considered “replacement parts” in California by
the California Air Resources Board (CARB), and do not require an exemption or executive order
from CARB to be sold in California. However, California prohibits the use of any aftermarket exhaust
system that modifies, removes or replaces original equipment catalysts, unless CARB has issued
an Executive Order as to such part or system.
Further, Akrapovič parts or exhaust systems used or intended for use on “racing vehicles” (i.e.
a competition vehicle used exclusively for competition on closed-course circuits) do not require
an exemption or Executive Order from CARB to be sold in California. However, such parts are
prohibited from use on California public highways or roads, even if occasionally used “off-road.”
