Not only does the 40 Series sound good, but it also helped improve my gas mileage a little bit also. It also helped my Jeep run a little freer compared to the factory exhaust it replaced.

Bettewr sound than stock and better mpg

I found that the flowmaster provided a nice rumble during low rpm's and was quite during highway speeds. After the initial reving and constant lead foot to hear the exhaust, when driven under the same conditions as stock muffer, will, on average, yield more mpg.

Truly American THUNDER!

Great replacement for the hum-drum stock mufflers. With my 5.4l, this tube rocks my Expediton. WOW!
