        I have a 6.5” Rough Country lift, will this affect my install and require me to make cuts?

        With the turbos in mind, will the chambered series 10 muffler have a negative impact on power beings it is not a free flowing muffler?

        • The 10 Series muffler included with the Flowmaster Outlaw Dual Exhaust System has very high flow, and has found to pair very well with the 3.5L ecoboost.

        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?

        • 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.

            Wicked Exhaust

            Being a V6 I was pretty skeptical about putting an exhaust on this but this system blew my mind. At idle it's a quiet rumble, in acceleration it gives a great tone, not to raspy like I thought. Under acceleration you will get a good amount of in cab noise but while cruising it is barely noticeable. All in all a great product!

            It grumbles for a V6

            Seriously I wasn’t expecting how good it sounds. Sounds like my Boss’ brand new raptor. I love it.

            Fits up tight and very clean looking. Sounds pretty good for an ecoboost, best I heard. You can really hear the turbos. Usually a bunch of bull, but I went on a 3,000 mile trip and did gained 2 mpg. Only issue I have is it is alot louder in the cab on acceleration than what you hear on any videos, cruising is perfect. May change muffler for that reason as gets annoying. Other than that this is a very nice system. My buddy who does exhaust for a living helped (has hoist) and he was very impressed with the fit and finish.

            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.

            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!
