Flowmaster Super 10 Series Mufflers Reviews


love the sound

Reviewed By Brian E (LAS VEGAS, NV) Reviewed for a 2006 Ford Expedition —6/29/2015 10:51 PM

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

Good quality, nice sound!

Reviewed By William H (Taftville, CT) Reviewed for a 2009 Ford F-150 —6/28/2015 6:21 AM

Solidly built muffler, the inlet & outlet ports are true to size so installation was a breeze. Excellent sound with that rumble I was looking for! I would recommend this muffler if you want your ride to sound a little meaner!

Reviewed By Tommy L (Ozark, AL) Reviewed for a 2009 Ford F-150 —6/27/2015 8:22 PM

This is the second f 150 I have installed the super 40 muffler on. Both have a deep tone and sound good.
