I am from bicycle engine factory.
I know so much about the EPA.
there is true EPA sticker and fake EPA sticker.
for true, there is factory name on the sticker,
for fake, there is no factory name on it.
for the engines, the true EPA will come with cat. converter.
so the exhaust is much heavier than the fake EPA kits.
if you wanto confirm your kits are true or not, you can balance your exhaust.
compare the pictures attached
