2019 Nissan Frontier SV
So just a week update... it sounds perfect! I really couldn't be happier. I would say its 5% to 10% louder overall. And the sound is smooth and deep. In my mind I really don't think you can get anything closer to the stock sound level. With the y pipe and flowmaster 70 series and tip. I have a whole new custom catback that puts out probably comparable power and alot less sound than the other premade catbacks. I paid $300 for all parts and installation. Can't beat that! Highly recommend!
