I noticed a huge difference after I hooked this mod up really easy install it goes in the trunk.
Keep the flaps open 100% at all times. Gives it a deeper sound and the pops at 5K RPM are louder.
The flaps only open 3/4 of the way if your under 60 mph without this EVM, this allows that 1/4 left to be open at idle and low speeds.
