sorry, i dont own a TRD
exhaust but i want to contribute my opinions.
Congrats on buying a great exhaust.
it might take a while for your car to get used to the exhaust, and as with any performance mod, you'll feel an increase in power.
it says in your profile, that you also have an AEM CAI
. well then, the exhaust should free up more HP for you now. you usually dont get the full potential of an exhaust by itself, which is why its always a great idea to have an Intake
along with an exhaust system. from start to finish, Intake
you might wanna check out some header for your car. that should complete your breather modifications
again, congrats on the TRD
exhaust and congrats on a great choice
