Going up thru the gears medium to high mashing- 1-5 bangs/cracks. Sounds awesome especially going thru a tunnel. Downshifting or engine breaking--race car like downshifts. This makes the stock or comp exhaust sound like a baby's fart. It's like did I shift gears? I guess i did. Lifting off throttle you just hear what the engine accomplished x5 ali g w turbo wind down. With our system you know exactly what's going on. All the while still extremely composed inside the car.
