Overall I love the Corsa Sport for my 6.2L Yukon Denali. It looks great and it definitely is a no drone system. The idle is a bit more aggressive than stock and cruise or mile acceleration is only slightly louder than stock with no drone. It gets more aggressive as you accelerate harder and sounds great above 2.5k RPM. In my opinion this system is never too loud. It sounds good but it is still somewhat conservative and fitting for a refined luxury vehicle.
