super 44 series
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.
love the sound
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
So far, so good! I was initially concerned about the db level that I would hear in the truck. The rpm range is limited for optimal rumble range for my Titan to be around 1500-2500. That is just what I was hoping for from my research. I really have not noticed any fuel rating increase as of yet. However, that is hard to judge due to the fact that I tend to stay in the rumble range when applicable.
