Loud and proud

Installed professionally, welded the tips just in case. Exhaust sounds great at an 11/10. Exactly what I wanted for my V8. Drone at speed and tons of fun under overpasses.

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.

  • We cannot confirm fitment for this on an F-250 as we have only tested this on the F-150 model trucks.

    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*!

    Review from Flowmaster Outlaw Cat-Back Exhaust w/ Black Tips - Split Side/Rear Exit (15-17 3.5L V6)

    If you want loud, this is it

    This exhaust is loud, but in a good way. Changes the truck completely. I would recommend two people or a lift. It's difficult maneuvering everything by yourself. In the end its worth it. The black tips look mean, and the sound you get adds to it. Quality of the pipes is very good. Instructions are helpful. Overall a great product.

    Beware of clamps

    Had to go to parts store to get clamps because the ones they give you do not tighten down and when you try to take them back off they stripped out. Word of advice Flowmaster - stainless steel U-clamps !!

    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!

    2015 f150

    Everything you would expect from flow master. The fit and finish was great. Instructions was very well written and drawn out. I installed myself took about 1 1/2 hrs with power tools. Sounds great at wot. And little to no sense at highway speeds. Note I installed on 2015 with the 5.0.

    Disappoint

    Had it installed on 29 Aug 2017, Im very disappointed in the sound. My 2016 Ford F-150 XLT sounds like one of those little cars. I do not recommend this exhaust, sound sucks. I have wasted $845.00.

    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.
