Installed the same muffler and am actually gettin 1mpg more than with the stock muffler, which doesn't make sense cuz I find myself in the throttle more just to hear that V6 groan !

I do try to keep it above 1800 rpm tho it sets up a harmonic inside the car that rivials the sub woofers behind the seats ! Other than that am well satisfied with the exhaust note.

Just my Dos Centavos !
