I got the NPP…pretty solid sounding exhaust. Not obnoxiously loud, and with Touring/Eco modes you can reduce that even further. My Camaro was pretty loud compared to NPP, this is classy. Screams when you want it to, and purrs when you like it to. If you want more than the below…go aftermarket. Disclaimer: This is NOT my car or me…but I do suggest mine sounds just as good!!!
