Muffler installed on nissan Rogue

Reviewed By Donna A (FAIRPORT, NY) Reviewed for a 2013 Nissan Rogue —10/19/2016 6:09 PM

This muffler is a gift from the loudest Gods. IT doesn't sound ricey at all and is all low. ITs louder then a Porsche. This is loud though like it will vibrate the car and you will ask people to speak up and you cant really hear people on Bluetooth and they cant really hear you but it is so worth. The start up is beatiful
