Review: Sounds great - 100% noticed increase in gas mileage. The sound it produces is great. Not obnoxious all the time. At constant travel speed its as quiet as stock but get on the gas and it has that great 5.0 deep growl. Couldn't be happier.
Review: GREAT !but don't expect great things...... - Ok, here's the scoop pull up a chair......... Install ~ Easy just take your time don't over tighten or strip screws easy peasy 25 mins MPG ~ I am sure it may have a positive effect as my MPG went from 17.8 to 18.2, HOWEVER... with the amazing throaty sound you get stomping on the pedal gas mileage will fall fast! Go easy it will save. Sound ~ WOW!!!!!! My 2013 F150 with the Coyote 5.0 really sounds awesome, get on the highway at 40-50mph and stomp it down and everyone in a 30 foot radius will look over and go WTF was that? LOVE IT!!!! HP ~ Haven't noticed anything but a little faster acceleration, nothing you will notice without a dyno tune! Price ~ Pricey, at almost $300 bucks I got the chrome pipe for looks, and for a pipe some gaskets and an air filter not sure I can say its worth the $$$.. Its your call, if you want your vehicle to sound and feel BAD ASS? Get it! if you want to save 1 mpg put $300 in your savings account instead :) In closing, I will say I Love it, and I feel it was worth it, heres a couple pics....

## Questions & Answers

**Q: K&n has this listed as 50 state legal. carb compliant. but amazon will not let it be shipped to my location in california, what gives?**

### ⭐⭐⭐⭐⭐ 2014 F150 XLT V8 fit great, MPG gained, louder than expected
*by J***N on June 4, 2021*

Super easy to install and even with me getting on it to hear the v8 roar now I've gained 2.3 mpg even with bigger tires and leveling kit. I did have to contact K&N due to one of the pieces being the wrong one. I had to wait till the weekday to call due to no customer support on the weekends but the guy was super helpful and expedited it so the new piece took maybe 2 days to get her. Defintly reccomend but its louder than you think it would be.
