    Can you Get Chrome Tips instead or Black Tips? How much horse power can you expect to gain with the new exhaust system? With this exhaust system will you get fuel millage increase and if so how much?

    MichaelT

    • It looks like we only have the outlaws available only with the black tips, chrome tips would not be available. Performance-wise you shouldn't look to get too much out of an exhaust unless you're looking at headers. This likely will not effect either power or fuel mileage and if it does, it will be minimal to the point where it goes unnoticed.

      Flowmaster Exhaust

      This exhaust is extremely loud. Much louder than in the video. It adds a mean growl to the truck that was missing before. Recommend if you want to be heard.

      "Awake your Monster"

      Little hard to put this beast muffler on without a garage lift, but my friend and I did it. This muffler turned my 3.5 ecoboost into a monster. Loud as sin when you hammer the gas and quiet as a mouse when you lay-off. You know how you drive down the road and fellow truckers come your way and they immediately hammer it to show-off. Well, this muffler tops all there trucks with its MONSTER GROWL it over powers them all. BAD AS*!

      Great Product!

      This product is awesome. I love the sound it gives to a 6 cylinder, also the installation was extremely easy. Flowmaster included easy to follow instructions in the package. The total time from getting tools ready, to taking the stock exhaust out and placing the Flowmaster on, to clean up and turn on took me about 2 hours. Some side notes: I did not use a vehicle lift so I had to cut my stock exhaust where it bent over the rear axle. Also when installing make sure you do not tighten any of the clamps all the way. You will need to make final tweeks once everything is installed.

      Love this system!

      Great sound when stepping on it, but quiet when coasting. Perfect mix. Highly recommended.

      3.5l EcoBEAST

      Exhaust sounds great, it took me about two hours to install on a shop lift. no welding needed, instructions can be found on flowmasters website. The exhaust sounds throaty and very beefy on cold startup. The drone is minimal on cruising highway speeds, but loud whenever you get on the gas! I am satisfied with the exhaust and would reccomed to anyone looking to make their ecoboost into a evobeast!
