"The installation was a breeze. I got nervous at one point though because the manual uses a different pt# for a piece but if you ordered correctly, which I did, it didn't matter. The sound isn't a big drone at any speed, but when you take off or put the petal through the firewall it sounds sick! I've already gotten many compliments on the sound. As far as performance the engine definitely breathes better haven't noticed an increase in fuel mileage, i've been too busy playing with it. Great value at a good price!" —Alexander C from Craig, CO bought a Banks Monster Exhaust System for a 2003 Mazda 6.
