super 44 series

Reviewed By donald d (FRESNO, TX) Reviewed for a 2014 Ford F-150 —7/8/2015 6:50 AM

The super 44 series flowmaster worked perfectly for what it is. I have a 2014 6.2l fx4 f150. The sound you get is amazing... although it's hardly louder than the super 40 series. So if you're going for loud I would go ahead and get the 10. My gas milage jumped up 2 miles per gallon. Great easy add on for any truck.

just right

Reviewed By Tim R (RADNOR, OH) Reviewed for a 2015 GMC Sierra —6/30/2015 5:52 AM

the 50 muffler is the right one for me and my sierra. it is just loud enough to let you know there is power under the hood, but it will not vibrate inside. unless you punch it, you would not notice it much. you can tell in normal driving it has more torque and horsepower.
