I love the sound of exhaust although it drones pretty significantly with the valves open. Valves closed there is almost no drone though. Very deep and aggressive sound much better than stock NPP.

Do you have a manual or auto? If the sound isn’t to my liking I may through on the borla resonators. The borla lines right up to stock so I’m not expecting figment issues
