They sound good. A little louder at cruise but no drone. With the windows up you can have a conversation without any interruption. To me it sounds a little more modern if that makes sense. It sounds like a hot little 340 now. The exhaust reflects the engine now. Open manifold cutouts next? Lol jk. My dad even likes it and hes a more mellow muffler guy. It sounds like a demon now lol
