Review on Khaos Motorsports Active Exhaust Delete/Simulator - USA Made! (Fits) Dodge Charger & Challenger 2015-2021 by Matthew Perez

Installation was very easy requiring minimal mechanical skill, just jack stands and a bit of common sense and you're done. It takes a few starts for the check engine light to go out while the car is being set up. My check engine light went out after 3 starts and rides. The car wasn't exceptionally louder, but removing the valves somehow eliminated the rumble my car had at lower speeds (I removed the center muffler), cold starts got a bit louder, and on pull the noise was 100% more than before. . but that's not much in my opinion, now the car is put right in front of the (annoying score). The car is noisy when you want it, but if you want quiet, just drive properly and it will be less noisy.
