<p>Enjoy the best of both worlds with Fabspeed's Lamborghini Aventador Valvetronic Exhaust; close the valves for neighborhood-friendly cruising volume or open the valves to unleash the full roar of the Lamborghini V12 while adding horsepower and throttle response.</p>
Hey guys 5500 for fabspeed
Is this a good deal?

Is it loud At idle? And clean sound?
Thanks in advance
