Absolutely unbelievable SOUND footage of a 2016 Lamborghini Huracan Spyder fitted with the and active valve exhaust (Klappenauspuff). While the optics are already modified through their aftermarket rims and some nice red contrast elements this exhaust modification is from another world....so unbelievable LOUD!!! The best part about it, you can also get this system ECE / EWG compliant so you don't have to be afraid of any police stopping you.
