However, with the resonator removal, i did notice the car having long periods of lag in acceleration when I suddenly step on the throttle (e.g. when you want to pass someone suddenly and you step on the gas). It takes a few seconds before it gets going.
I believe the reason is that the resonator is designed with an air resovoir (a huge box shaped thing) that allows air to sit. With sudden increases in throttle, it will take a huge gulp of air from the air resovoir. If you remove the resonator, it will take a while to collect enough air to feed the sudden need for more air with sudden increases in throttle. Maybe an analogy would be like holding a gulp of air in your mouth that if you suddenly suck in air you have that air ready and sitting in your mouth. Whereas if you suddenly suck in air with your mouth already open, there is a slight vaccum created at the moment you suddenly start sucking in air. This is all just theory by the way... I could be wrong.

Mine is more responsive without resonator. That reservoir is there so that the vibrations of air would be killed off in there. It's true tho, K&N filter is what bring this thing to life, but I run paper for better filtering.
