Finally Completed Full Agency Power Exhaust
Just put on their headers today guys, it sounds amazing! I will post up videos within the week! Absolutely love them, and their valvetronic system works wonders, when you want it to quite down you close the flaps and it's just a bit rougher of a note than stock, one question though guys, I notice that after a certain RPM they completely go dead silent, there is no performance loss, it just sounds loud as hell and then until the car shifts they are very silent, and then back to loud again on the next gears lower rpm's, input?

of course petro, that is a given, i love the feature and they tone down to a perfect point, i am referring that mine do this in higher rpm's with the flaps open, perhaps it's because they haven't broken in yet? videos tonight btw guys, will post up a new thread, thank you petro
