This muffler sounds amazing I love the deep rumble it gives at both low and high rpms

Recieved the muffler in two days. Had it installed the next day. the sound is loud and powerful, most of my friends have said it makes my Expedition sound like a Shelby Mustang. I have seen an increase in power and torque. Dont know if theres an increase in MPG because I lay my foot into it a bit more now just to hear that beautiful growl
